The Norfolk Portraits

1932: The Wedding of Ernest and Ivy This image is an AI restoration and colouring of a 1932 wedding photo capturing the marriage of my grandparents, Ernest William Curtis and Ivy Maud Tovell, at Limpenhoe, Norfolk. This project tracks the direct matrilineal line, represented here by the bride and her mother, Caroline Tammas-Tovell, who is seated beside her.

I have mapped a hypothesis of the route my mitochondrial DNA (mtDNA) has taken over approximately 1,000 generations. This journey commenced with the emergence of "Helena" 25,000 years ago in the Levant and concludes with my mother in a Norfolk village.

A Childhood Snapshot This is an AI restoration of a snapshot of my mother as a young girl, being "forced" to pose with a kitten by her brother, Dennis.

The Biological Engine: A Story of Fluke and Resilience

Mitochondria are a story of fluke and resilience. Billions of years ago, they were likely independent bacteria. At some point, they were engulfed by a larger cell but escaped digestion; instead, they formed a symbiotic partnership. The mitochondria provided energy, and the larger cell provided protection. They became the power plants located inside almost every cell of our bodies. Just as a city needs electricity to keep the lights on, our cells need a specific kind of "chemical energy" to keep us breathing, moving, and thinking.

Because they reside in the cytoplasm, outside of the central nucleus, they contain their own autonomous DNA. It is the mutations or variants on that mtDNA (in my case, Haplogroup H6a1a8) that I have been following. For geneticists, mtDNA acts as a vital marker; we can date variants and pinpoint their emergence to a specific time and geographic location. It is uniquely useful because, unlike nuclear DNA, it does not recombine or "shuffle" with each generation. Rather, it follows a strict line of descent. Traced backwards, it follows my mother, her mother, and her mother before her—along that unbroken matrilineage, all the way back to "Mitochondrial Eve".

A Legacy of Resilience: The Cache County Study

For students of Integrated Ancestral Studies (IAS), however, this is more than just a marker. It appears that those of us carrying H6a1a, H6a1b, or their descendant "daughter" lineages (such as H6a1a8) may have inherited a significant biological advantage.

The Cache County Study on Memory in Aging—a long-term investigation involving over 1,000 residents of northern Utah—sought to understand why Alzheimer’s disease (AD) clusters in families and why there is a notable "maternal effect." Researchers discovered that individuals belonging to the H6a1a and H6a1b sub-branches of the Helena lineage had a significantly reduced risk of developing Alzheimer’s.

While the exact biological mechanism is still being researched, the findings suggest that these specific mitochondrial lineages are more "resilient" to the ageing process. Their variants are located in genes responsible for the electron transport chain—the machinery that generates cellular energy. For this project, it adds a profound layer of meaning: the route this DNA took over 1,000 generations isn't just a map of migration, but a 25,000-year-old legacy of cognitive resilience. This may explain why Alzheimer’s has plagued my paternal line, yet remained notably absent from my maternal family.

The Journey of the Matrilineage

Matrilineal Staying Power From the perspective of human population genetics, I have noted the remarkable resilience and "staying power" of women across prehistoric societies. Men come and go, but the mtDNA remains. Consequently, Europe has become a broad matrix of diverse mtDNA haplogroups, while a relatively small number of Y-DNA haplogroups dominate. Warriors arrive and are later vanquished, but those who actually till the soil and produce often remain as the enduring genetic background.

The Norfolk Thread Records show that my matrilineage has been incredibly localised in south and east Norfolk since at least 1661 CE. I find it highly probable that the line was present there during the Late Medieval period, and I have further postulated that it may have lingered in this area as far back as the Iron Age. While these theories are based on rational conjecture—factual certainty only begins with that 1661 baptism—the proposed 25,000-year route suggests many instances of "settling" for centuries or even millennia. I view mtDNA as a genetic thread that weaves different cultures together.

H6a1a8: An Iron Age Haplogroup Throughout this journey, I have associated H6a1a8 specifically with the Western and Central European Iron Age. The clues exist in ancient DNA samples found in North Berwick, Scotland, and in its modern distribution. I hypothesise that my matrilineage likely entered the British Isles following the Late Bronze Age migration events from the south, but prior to the Anglo-Saxon "North Sea Migration Continuum."

Admittedly, I may be simplifying these movements. The journey may not have always been a linear "westward" trek from the Volga; the reality is likely far more complex. What I have attempted is to narrate a believable route through 25,000 years, acknowledging that many alternatives may exist.

Ovum Act 3

Images of my 190 times great-grandmother as visualised with a lot of prompting and correcting by Google Gemini.

Meet my 180th great-grandmother. Her personal name is Hen-at-yah. We can reasonably speculate on this because she almost certainly spoke an Indo-European language—the ancestor to most modern European tongues. The year is 3000 BCE, and she belongs to the archaeological group known as the Yamnaya culture. Her mitochondrial DNA (mtDNA) haplogroup is H6a1.

Beside a wagon burial, Hen-at-yah bids farewell to her late husband. She is now the widowed matriarch of her family. Her husband’s remains will be covered by a massive mound of earth—a kurgan—serving as a permanent memorial to a great man. Wherever these people have roamed across the Pontic-Caspian steppe, they have left the landscape littered with these monumental burial mounds.

They are a metalworking people who long ago mastered copper and are now experimenting with its alloys. Living along the "Steppe Corridor," they have been exposed to innovative ideas from both east and west. They have adopted sheep, goats, and cattle from the Fertile Crescent south of the Caucasus, and from the same regions, they refined their metallurgical skills.

Crucially, they have utilised the first domesticated horses of the Eurasian steppes and combined them with the invention of the wheel to create their own wagons. These are a nomadic people; their wealth lies in their livestock, and they roam the endless grasslands to guide their herds. In this mobile, pastoralist economy, their wagons are not just tools—they are the very foundation of their way of life.

Hen-at-yah buries not only her husband but also her connection to the vast grasslands her family has roamed for generations. The Yamnaya have mastered the exploitation of dairy; this nutritional breakthrough has led to a surge in population, and with it, intensifying disputes over grazing rights. She has heard travellers' tales of a great plain far to the west—a place of lush grasses sheltered by mountains. Hen-at-yah promised her late husband that she would lead their folk to this whispered paradise.

This "plain" is the Pannonian Plain in modern-day Hungary. Her journey represents the monumental migration of nomadic herders from the Pontic-Caspian steppes into the heart of Europe. Most modern Europeans of local descent carry a significant genetic legacy from this event:

Region Estimated Yamnaya DNA Typical Populations
Northern & NW Europe 38% – 50% Norwegians, Scots, Irish, Icelanders
Central & Eastern Europe 30% – 40% Germans, Poles, Lithuanians
Southern Europe 18% – 32% Greeks, Spaniards, Mainland Italians
Mediterranean Islands 2% – 12% Sardinians, Sicilians, Maltese

The most common Y-DNA haplogroups of European males—dominant even in Western Europe—are direct descendants of R1 (R-M173), a lineage that arrived with the Yamnaya Horizon.

Whether measured by autosomal DNA (general ancient ancestry) or Y-DNA haplogroups, Western Europeans—particularly those from the North West—possess substantial Steppe ancestry that reached Europe between 3000 and 2500 BCE. On my direct paternal line, I am an exception; my yDNA arrived from south of the Caucasus in South West Asia much later. However, my mtDNA (mitochondrial DNA), inherited through my direct maternal line, did arrive during this Chalcolithic migration. H6a1 is effectively the maternal sister-line to the R1a and R1b paternal lineages that reshaped the continent.

They had lived on the Pontic-Caspian steppes, developing a distinct economy and a subsequent culture. Their belief systems, concepts of wealth, and social structures were perfectly adapted to that expansive environment. They brought to Europe more than just their DNA and the Indo-European languages (the ancestors of modern English, Gaelic, German, French, Spanish, Italian, and Russian); they brought a technological revolution.

With them came advanced skills in working copper, gold, and bronze. They brought the wheel and, almost certainly, the horse. They also introduced new religious beliefs centred on celestial deities: the sun god and the storm gods of the vast, open steppe sky. These were the myths and rituals they practised while huddled around campfires, carryovers from a world where the horizon was endless.

Ovum Act 2

Meet a great-grandmother from 250 generations ago. She carries the mtDNA haplogroup H6, or perhaps H6a, in trillions of her cells. She is a descendant of the 'Basal Helena' we met in the Levant 25,000 BCE. But this grandmother lives on the banks of the Volga, in what is now southern Russia, and the date is 4,500 BCE.

5,000–4,500 BCE), the Khvalynsk culture

She is no longer a nomad of the caves. Here she belongs to a world of copper, cattle, and sheep—the first great social hierarchies of the steppe. The ancient spark from the Levant has adapted to the cold winds of the north.

Our 250-times great-grandmother is not a wife of the Fertile Crescent Neolithic, nor have her people abandoned their Eastern Hunter-Gatherer roots. Instead, they have adapted to a way of life unique to the steppe. The herds they once hunted, they now master. They take from the Fertile Crescent what they need—sheep and cattle—but they do not toil the soil. They are women of the great Eurasian Steppe. They are becoming the great pastoralists; the herders of the endless grasslands

This ancestor belongs to an archaeological layer which Russian researchers have named the Khvalynsk culture. It is a period defined by a pivotal shift: the move away from hunting, fishing, and foraging towards the pastoral herding of cattle, sheep, and goats.

These herds introduced the concepts of private property and surplus value to their economy—a newfound wealth that seems to have stratified their society. While some of their graves were laden with status objects, such as polished stone maces and copper bracelets, rings and pendants, others remained starkly bare.

The Great Eurasian Steppe serves as the continent's primary thoroughfare. Across these vast grasslands, new cultures, languages, and peoples—alongside their livestock and technologies—surged east and west, linking Europe, the Caucasus, and Central and East Asia. The people of the Khvalynsk culture were a product of this flux, carrying the genetic heritage of several previously isolated populations. These included hunter-gatherer groups local to the East Europe and the Eurasian Steppe, from the Caucasus, and from as far away as Siberia. Our 250th great-grandmother’s matrilineal lineage once resided on the Iranian Plateau before embarking on an arduous trek far to the north. Her arrival on the Volga helped forge a new way of life, blending southern traditions with the rugged spirit of the northern plains.

Discussion

Although this is based on limited samples (albeit rapidly growing samples over the past year), there is of mt haplogroup H spread across Western Eurasia, certainly by the Mesolithic period.  Today, it is the most common haplogroup in Europe, found in 41% of Europeans.

H6 however, is less certain.  It has been suggested that it is more frequent in Eastern Europe, and the Caucasus.  The above ancient DNA references, collected so far, might suggest that H6a1 arrived into Europe with the Yamnaya expansion off of the Eurasian Steppes, carried by Steppe pastoralists migrating westwards, during the Copper Age / Early Bronze Age.  H6a1a itself, first appears in the Corded Ware Culture, which has recently been recognised as a fusion culture, that developed in Eastern / Central Europe, as a result of the arrival of the Steppe pastoralists.

The samples above suggest that H6a1a was present in Britain previous to the Anglo-Saxon period, and was also present in Medieval London.

2017-01-04 UPDATE


I received my FT-DNA mtDNA Full Sequence test results.

Confirmed H6a1a8.


Matches mainly North America and Australasia without many Old World provenances.  However, I'm getting the distinct impression that it's been in the British Isles for some time.  I'm starting to research, but I'm seeing England, Ireland, Wales, maybe Finland.

Using the above Behar et al dating of H6a1a8, I age this haplotype to between 1970 BC and 1825 AD.  It's not old, although most likely late prehistoric.  It must have formed after Corded Ware, Unetice, etc.  Might date towards the end of the Bell Beaker Culture at a stretch, but most likely later - Iron Age perhaps?

My main interest is origins, with genealogy only as a bonus. I'm interested in knowing where H6a1a8 originates! H6a1 has been found in Yamna context. H6a1 and H6a1a have been found in Corded Ware context. No earlier H6a1 found in European atDNA. So it appears likely, that H6a1/a was an mt DNA type that followed the many Y-DNA types of the Copper Age Steppe migration across Europe - despite the usual dominance of Steppe Y haplogroups in Western Europe that indicate a male sex bias. 

Behar et al., 2012b, dates H6a1 to 8,669.7 ± 1,905.2; CI=95%, H6a1a to 7,139.5 ± 1,993.2; CI=95%, and H6a1a8 to 2,023.7 ± 1,898.9; CI=95% So I see H6a1a8 as pretty young, most likely Bronze Age or Iron Age. I'm curious as to when it distributed through Europe, and when it likely entered the British Isles. My mt-line has been in Norfolk, England for at least 290 years, when my earliest mt ancestor, Susannah Briting was born. She married my ancestor at Bunwell, Norfolk in 1747. I'd say that the probability is that it had been here in East Anglia long before that paper trail. So when did it likely move here?

23andMe had previously tested me to H6a1. Both the James Lick mthap analyser, and WeGene, looking at the 23andMe raw data, took that to H6a1a8. They were correct:

The FT-DNA mtFull Sequence confirmed my mt haplogroup to be H6a1a8.

My HRV1 mutations are: A16129G, T16187C, C16189T, T16223C, G16230A, T16278C, T16298C, C16311T, T16362C, A16482G, C16519T
My HRV2 mutations are: G73A, C146T, C152T, C195T, T239C, A247G, 522.1A, 522.2C, 309.1C, 309.2C, 315.1C
Extra mutations are: 309.1C309.2C315.1C522.1A522.2CC16519T

HRV1 matches are:

England 3
Hungary 1
Ireland 4
UK 1
USA 1

HRV1 + 2 matches are:

England 2
Hungary 1
Ireland 3

I have a "HRV1, HRV2, and Coding Region" exact match: Ireland 2

On Matches I get four GD0, but all appear USA/Aus, etc. I have emailed them. Three replied. No paper or geographical correlations. They can't follow their mt lines previous to emigration. They could come from anywhere in Europe, although English surnames keep dominating on their maternal sides.

On Matches map, a little more hope:



I've joined the H6 project, but being a development of the pretty massive mt hg H Project, it is drowned in submissions, with a long waiting queue of "ungrouped". The only other H6a1a8 on the results is USA. There is a H6a1a8a ungrouped as private located as "Finland", and another H6a1a8a located to Wales.
