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.

Closing Log

I hope that someone finds the Ovum series useful, today or tomorrow. This is the personal journal of a Time Traveller left open.

To follow: 

an index bringing together Ovum (my mtDNA narrative) and Odyssey of Y (my Y-DNA narrative). From there, I shall move on to other subjects within Integrated Ancestral Studies, including:

• Restored and colourised photos of my late uncle's Korean War tour. The 1951/2 Royal Norfolk Regiment in colour. National Servicemen in action.

• Viscount Melbourne as Home Secretary personally petitioning for the release of my swing rioter ancestor. The incredible pardon from transportation by the man who a few years later transported the Tolpuddle Martyrs. By his whim alone do I exist today.

• AI for time travel. Strengths and weaknesses.

• Reflections on a forty-year journey through the tracing of ancestors.

• My 18 year old Boer War veteran ancestor of the 9th Foot.

• A fresh look at my late father's metal detector finds from Norfolk, and what they suggest about the boulder-clays of the East Anglian Plateau.

• Identifying struck flint and prehistoric stone tools

• Idyllea: Revisit my adventure tale of three siblings at the close of the Mesolithic period.

• Local history, archaeology, genealogy, genetics, prehistory and more.

If anyone finds these logs one day, then enjoy.

This is an AI restoration of a photograph of my great-great-grandmother, Sarah Ann Thacker (née Daynes), sitting with my great-great-grandfather, George Thacker. Sarah was born in 1849 at Besthorpe, Norfolk, close to where her ancestors had long resided in Carleton Rode and Bunwell.

The grandeur of this studio portrait is somewhat misleading. Since the time of her own great-great-grandmother in the late 17th and early 18th centuries, the carriers of our H6a1a8 mtDNA matrilineage had suffered a marked decline in economic and social status. This decline was mirrored across my entire family tree between the 1770s and the 1870s. Parliamentary enclosure, the New Poor Laws, and the exploitation of the North American plains and Russian steppes squeezed these descendants of the medieval period. They were transformed from free tenants, yeomanry, and copyholders into the impoverished ranks of 19th-century agricultural labourers. In the process, they lost their ancient ties to the land and were forced to avoid the workhouse by selling their labour to the few who retained ownership.

These were harsh times, and they were not always accepted passively. Some of my non-mtDNA ancestors were involved in the 1830 Swing Riots. Others ended up in Union workhouses or prisons, while many emigrated to northern cities (frequently Hull), moved to London, or headed abroad. The story of my East Anglian ancestry, including my mtDNA matrilineage, is one of resilience and fortitude. We are descended from the small minority who stayed put.

This is an AI restoration of a photograph of my great-great-grandmother in her later years. I imagine the cottage behind her was at Green Lane Farm, Rackheath, Norfolk.

Impoverishment had stimulated movement. Sarah married George Thacker, who lived in Rackheath—a rural Norfolk parish on the opposite side of Norwich—and moved there to join him. For many years, they lived at Green Lane, where they raised no fewer than ten children between 1871 and 1893.

A somewhat cruel story is attached to Sarah’s memory. Family folklore suggests she was a strict disciplinarian. It is said that when she had to leave the children unattended, she would tie them to chairs with strands of cotton. Upon her return, if the threads were broken, she would physically punish them. "Granny Thacker by name, thacker [to hit] by nature," goes the family saying.

She passed her mtDNA down to my great-grandmother, born in 1878 and named Drusilla Caroline Thacker.

This is another AI restoration; from my own memory, I remember that face well. This is Caroline (who preferred it to Drusilla)—Caroline Tammas-Tovell by nature. I have had Gemini place her in front of Southwood Hall Farm, Southwood, Norfolk, because once again the matrilineage moves across the county—this time to the loamy soils of East Norfolk. There, she married into a rural, working-class family whose roots had been established on the edge of the Halvergate Marshes and along the River Yare for several centuries.

As I mentioned, I knew my great-grandmother before she passed away in 1971. I would meet her at my grandmother’s house; as a child, I was in awe of the fact that she had grown up in the age of Queen Victoria. It felt like an early taste of time travel. She would pay me a pre-decimal sixpence to kiss her. Strangely, I can still recall her voice.

My own mother grew up in the Southwood and Hassingham area of East Norfolk, where, in time, she met my father, who hailed from East Dereham in Mid Norfolk. This brings me to the end of my "Ovum tales" of mitochondrial ancestry: from Helena in the Levant, 25,000 years ago, to Norwich, Norfolk, sixty years ago—and onward through the younger generations. The "Selfish Gene" continues its long story.

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.
