yDNA haplogroup L in Medieval Cherry Hinton, England

Cherry Hinton, Cambridgeshire, James Alexander Cameron on Flickr

Most of our nuclear DNA recombines with every generation. But a yDNA Haplogroup is a genetic marker that follows along the direct paternal line, passed down from biological father to son. Follow it back, and it will follow your father's father's, father's, etc.  Most NW European males carry a yDNA haplogroup of R, or I. Sometimes G, J, E. However, I have a variant of L, defined by a mutation coded M20 (L-M20). yDNA haplogroup L is regarded as Non-European and some will insist that it is South Asian. I can reliably trace my own paternal line back to 18th Century Oxfordshire / Thames Valley.  yDNA haplogroup L is NOT seen as European. It is seen as an Asian genetic marker. The males of two English families share my own mutations: BROOKER of Oxfordshire and CHANDLER of Basingstoke, Hampshire. My next closest yDNA matches are men from Iran, Iraq, Saudi Arabia, Turkey, India, and Lebanon. 

Cherry Hinton, Cambs.

Excavation of a Medieval Cemetery. Ancient DNA revealed.

Consequently, when I saw that FTDNA had given me Ancient Connections from here in England, I at first thought it a mistake. Yet there they were, two excavated skeletons from a medieval cemetery in Cherry Hinton, Cambridgeshire.

Were they relatives / ancestors of the Brooker and Chandler lines?

I investigated. These two human remains dating between 940 CE and 1170 CE, and coded Cherry Hinton 919 and 936 had the M349 and B374 variants. I can best demonstrate our paternal relationship by a plan:


The most recent mutation shared by both myself, and these Medieval Cambridgeshire Men, is M317. The TMRCA (Time of most recent common ancestor) to all descendants, is I'm afraid, 12,700 years ago. The M317 variant first formed 18,100 years ago. Therefore, I and the Cherry Hinton men, last shared a common paternal line at the end of the last Ice Age. I would suggest that our common yDNA ancestors lived somewhere between Anatolia, Syria, Afghanistan and Pakistan. Both my own SK1412, and their M349 formed around 12,700 years before present. We cannot share our direct paternal lines before 10,700 BCE.

What do we know about these Medieval men? I have scoured the excavation reports and data sheets:

Genetic history of Cambridgeshire before and after the Black Death

'In total, 48 individuals from Cherry Hinton were targeted for DNA extraction in this study, including 24 females and 24 males (Table S1). Two of the sampled individuals have been directly radiocarbon dated.'

'Cherry Hinton The settlement of Church End Cherry Hinton (Cherry Hinton) is located around six kilometers southeast of Cambridge. In the late 9th to the mid-10th century, a large thengly (aristocratic) or proto-manorial center was established (92, 93). The associated timber chapel and graveyard were excavated in 1999 by the Hertfordshire Archaeological Trust (subsequently Archaeological Solutions and now Wardell Armstrong) in advance of development of the site in accordance with the appropriate planning regulations'

More on the excavation in this Current Archaeology report.

Cherry Hinton 919 (sk3262) was related to a female (mother, or sister?) number 947 (sk3262) with whom he shared his mtDNA haplogroup U5b3e His yDNA was sequenced as L-B374.

Cherry Hinton 936 (sk2077) had no close relatives (albeit had to have shared his paternal line with 919). His mtDNA was T4b4+152. His own yDNA was also L-B374.

Both sequenced from tooth root; classed in Rural 4 group; dated between 940 CE to 1140 CE

The route of their yDNA was: L-M20>M22>M317>M349>B374. See plan above.

The route of the modern BROOKER / CHANDLER lines is: L-M20>M22>M317>SK1412>SK1414>FGC51041>FGC51036

 L-B374 Today

Only one modern English, or British tester, has so far tested on ftDNA, or registered on yFull with a result of L-B374.

The only modern Asian samples have been a single tester from Kazakhstan. Rather, the highest density of testers have placed their paternal lines in Switzerland, The apparent centre of modern L-B374 - this variant looks very European. The TMRCA for B374 is 600 BCE. Following Switzerland, it has also been reported in: Germany, Austria, Czech Republic, Tatarstan, Slovakia, Slovenia, Hungary and Croatia.

This is not the case with my own variant (L-FGC51036). Other than the two South English families, our closest yDNA relatives have been from Lebanon, Saudi Arabia, Iraq, Iran, India, and Turkey. Our own line arrived independently, and possibly later than that of the Cherry Hinton Men. I propose an Early Medieval date for the arrival of my own paternal line in England. Maybe one day we will get as lucky, and our own paternal line ancestors will be excavated?

Documentary Paternal line.

I have proven descent from John Henry Brooker, through genetic matching to support the documentary evidence. I and my sibling share some centimorgans of autosomal DNA with descendants of his sister. Additionally, smaller segments are shared from the prior few generations, to support that this paternal line is biologically true, at least back to Generation 5 (great great grandparent). He was the only one of my great grandfather's not to be Norfolk-born.

If I follow his paternal line (BROOKER) back using traditional genealogical method, I follow it back to the Thames Valley borderlands of rural Oxfordshire and Berkshire. I have good, strong documentary evidence back to my direct paternal line 5 x great grandfather, Edward Brucker, born 1757 at Long Wittenham, Berkshire.

Support for my 6 x great grandfather being a John Brooker born 1722 at Hagbourne, Berkshire in 1722 is pretty good. His father before him I have verified, was another John Brooker born 1691 at Hagbourne. His father was Thomas Brucker, also baptised at Hagbourne in 1658.  If biologically true, he would be my 8 x great grandfather and that would place my Y chromosome in Hagbourne, Berkshire in 1658. The Chandlers who share the yDNA descend from a Thomas Chandler who lived in Basingstoke, Hampshire during the late 18th century. At some point prior to that, our two paternal lines must merge.

Anything earlier than 1658 Hagbourne, too much doubt creeps in, but I have candidates stretching back a few generations waiting for more supportive evidence. They are in the Wantage/Uffington area of Oxfordshire. Caution - they may be incorrect. Another candidate in in Whitchurch, Hampshire.

I've researched the BROOKER surname:

Distribution of BROOKER baptisms AD 1550 - AD 1600 by English County.  County boundaries modern, but East and East Surrey united for historical purposes.  Includes records of derivations of Brooker surname.

During the 16th Century CE, it was not a common surname in Oxfordshire and Berkshire. Its origins are the Sussex / Surrey area. It is possible that I had a Brooker surname ancestor move up through Hampshire into the area. I think that our surname picked up the yDNA in Hampshire, or in a South English port. My favourite hypothesis is that a South West Asian sailor visited, and left a son there early into the Medieval.

This hypothesis might seem unlikely, yet it brings me to:

Updown Girl

In my previous post concerning Anglo Saxon DNA, I discussed this report:


A 2022 survey, where hundreds of ancient human remains were sequenced for DNA. My favourite treasure of that study, came from an Anglo-Saxon grave in Kent. A girl, who had died during the early 7th Century CE (600s) around the age of 11 years of age. She was buried with Anglo Saxon artefacts, with full respect. She was related to some other nearby individuals (great aunts?) who had artefacts suggestive of Frankish origin.

On sequencing UpDown Girl's DNA, it was revealed that 33% was West African in origin!  UpDown Girl most probably had a grandfather from West Africa. Her DNA was most like the modern Esan or Yoruba population groups.

This is another example of why we should be very wary of not generalising. There were always a few travellers who would move far from home. It could be that my Asian sailor was another one, like UpDown Girl?
