More Ancient DNA ….
开云体育Hello againI hope you all have enjoyed a happy Christmas. Here is another interesting article describing how autosomal DNA technologies, similar to those used by Ancestry and FTDNA Family Finder, can be applied to analysis of ancient populations? Best wishes Nigel |

Greetings fellow R-S16264s
I hope all is well with all of you. I continue to look out for potential new recruits to our group but little has changed over recent months and even years. However the science continues to develop, particularly ancient DNA studies of human remains recovered during archaeological excavations. The link below is a very interesting example of how much information can be recovered from just one ancient individual. I hope you enjoy reading about him. Best wishes to you and your families for the holiday season Nigel |

Re: Renaming R-F110 to R-FGC36619
Thanks Wendy.? I should also have mentioned Jenny Grillet's Edward Schultz.? He is F110+ but FGC36619- so would remain R-F110 if FTDNA are able to reassign the DF21>DF5 F110's using another of their shared SNPs.? Otherwise Edward Schultz would have to be relabelled R-L679 until more testing is done to identify more recent SNPs he shares with myself and Larry Brett.? That would require BigY700.
Kind regards Nigel |

Renaming R-F110 to R-FGC36619
Larry Brett (Wendy Morse's uncle) and I are currently assigned to haplogroup R-F110.? Most Y-DNA SNPs which are used to define haplogroups have occurred only once in the history of mankind and so can be used to define branches in the Y-DNA family tree without any risk of duplication.? Unfortunately, F110 is not such a SNP: it is a recurrent SNP which has occurred more than once and in more than one branch of the Y-DNA tree.? Until recently other occurrences were not being used for naming haplogroups but that is no longer the case - I have found there is another R-F110 in a different part of the Y-DNA tree (DF21>DSF5 .... but like S16264 also derived from L21+, DF13+).? So I have sent a note to FTDNA pointing this out and suggesting our R-F110 be renamed R-FGC36619 as FGC36619 is unique to Larry's and my branch of the Y-DNA tree.? Hopefully the change will happen within a week or two.
Best wishes Nigel P.S. Please post anything you think might be relevant to S16264 research including news of new matches or any new learnings about your Y-DNA ancestral origins. |
FTDNA Discover Tool
Greetings If you have logged on to your FTDNA account recently you may have noticed a new tab in the Y-DNA Results section of the Home page.? This is the new 'Discover' tool which presents information on the branching SNPs in the Y-DNA tree including date estimates for when these branches in family lines occurred.?? In the attached .pdf I have extracted the data for our line of descent for the last 4,450 years:? - I start with R-Z39589, 'son' of R-DF13, who lived early in the European Bronze Age. ?? - The next branching SNP FGC59881 is new discovery since our Yahoo Group ceased to exist in late 2019. - Our S16264 is one of 3 known surviving descendants of FGC59881. - BigY testing in the last 3 years has found early branches in the S16264 family which were previously unknown - see the .pdf for details. - I will try to find more information on the people whose BigY's discovered those branches as they may provide more clues on the ancient geographic origins of S16264 (which I still believe is likely to be northwest France, in Bronze Age Armorica). - Rod Mann's line, R-Z16861, is estimated to have split from the line leading to the R-L679 family c.200 BCE i.e. in the Pre-Roman Iron Age - The R-L679 families [Turner/Hammond] and [Bond/Brett/Schultz] split c.1450 CE - The R-A7314 Turner-Hammonds split c.1650, consistent with known history - The R-F110 families Bond-Brett-Schultz split c.1800.? My paternal ancestry and that of the Schultz line is unknown at this date.? Larry Brett's ancestor Samuel Brett was born in Dorset, England in 1806 and by 1826 was in Newfoundland.? I hope Wendy doesn't mind me asking but might both Bond and Schultz be descended from Samuel and/or one of his close relatives? - Bob Hawk's R-BY42718 line split from that leading to his closest BigY match c.650 CE.? Bob - have you been able to find out more about this distant cousin? Please let me know if you have comments or questions. All the best Nigel |

I noticed him too but don’t know if there is any way to contact him. It would be good to find out more. I am traveling at the moment but hope to get back to S16264 matters when home again in a couple of weeks. Nigel On 11 Sep 2022, at 17:27, Edward Hammond <manager@...> wrote: |
new S16264+ kit?
Hi Everyone -
Have I noticed a new S16264+ kit at yfull.com, ID YF108578? I'm not sure if this a genuinely new result, or if perhaps has somebody that we already know has recently submitted their result to go on the yfull tree? (I am the "new" R-L679 - YF107964.? I didn't submit results to yfull until recently.) Edward |

Attached is the block tree I see at FTDNA for my Big Y 500.? Nothing new that I am aware of. I've had a number of new STR matches, but I don't believe there is anything new there either.? An image of matches sorted by date is also attached. EH On 8/9/22 2:45 AM, Nigel B via groups.io wrote:

Welcome … and a Matches request
?Greetings to all R-S16264s. Thank for joining our new group and thank you to Edward for setting it up. I hope you and your families have come through the recent very strange years safely. Like many others I and my close family have all had Covid but all have thankfully recovered.
Edward and I decided to restart the group as we think it is important to keep in communication even though the pace of developments in learning more about our DNA family is extremely slow. We remain a very small group of proven S16264 related people. A few more distant S16264s and cousins who have been found by FTDNA testing (more of that to follow in another note). FTDNA‘s revised privacy rules (and maybe the testers personal preferences) make it extremely difficult to find out more about them and to invite them to join us. Fewer new testers are joining DNA Projects with ‘public’ access to their Results pages so we can not easily take the initiative to find and contact them. One way for us to learn more of our S16264 family histories is to share information on new DNA Matches. Any new Y25, Y37, Y67, Y111 or BigY matches are potentially of interest. Please check. If you have any new matches since say 2016 please contact them and invite them to join our group. Also please let us know that you have these matches. It is good to be in contact again. I will send an e-mail on known S16264 developments later in the week. Best wishes Nigel |
Re: Greetings
开云体育There will be some spectacular failures when erroneous
genealogies are widely replicated and feed too much garbage into
the AI, and when there are uncanny genetic similarities that occur
in isolation of one another, but I'll bet these (sometimes
frightening) machines will fairly quickly develop the ability to
filter out the vast majority of bad genealogies.? It feels to me like the situation may parallel the time 25-30 years ago when the majority of the human genome was dismissed as "junk DNA" by scientists, mainly because they couldn't determine its function.? In the same way, we effectively dismissed autosomal DNA for serious genealogical purposes because of the all the recombination.? But rather than rendering it meaningless, maybe all the mixing just rendered it too complicated for our, uh, single core processors (brains) to manage.? Whereas if you have dozens or hundreds of threads that you can hold in your (electronic) brain at once, relationships appear... Optimistically, Edward

Re: Greetings
开云体育Sorry, I'll stop now... but imagine when you can bridge to Sandy
Mocilan's other faint contacts that might bear "Hammond"
centimorgans that I've lost.? Hell, for all we know now, Sandy Mocilan may have a faint autosomal match to a Turner, or a Braginton. I bet it doesn't take that long for it to be figured out how to make those sort of connections 'in silico'. It's funny, in my day job one of things I am paid to worry about
it all the exabytes of DNA sequences of plants, animals, microbes,
etc... that have no geographic origin ascribed to them.? I was
just talking last week with a data scientist about the idea that
you could probably, quite soon, unleash an AI on a massive
biodiversity sequence database and have it figure out how to more
or less reliably tell you where each sequence came from.? In a similar way... EH

开云体育There's my best Hammond example of a nice machine learning
match.? I would never have been able to link Sandy Mocilan to myself on
the basis of a tiny genetic match (10cm) with anything less than
her (him?) having a well-developed genealogy.? I haven't run down Sandy's line myself, but it looks plausible.?
In effect a probable 7th generation link made possible by AI. Maybe not revolutionary yet, but I suspect we're at the early
stages. EH

Re: Greetings
开云体育On a slightly different note, have you noticed how AI / machine learning seems to be producing some pretty interesting results at ancestry.com?? I'm not crazy about yet another pay site, but I've been amazed by its ability to (seemingly ... I haven't fully proofed very many) accurately match rather distant autosomal hits.? The sort of people that you scroll by in the autosomal results at FTDNA and think "that one just isn't worth pursuing". EH
