Hi Robyn and Vosper Cousins,
Over the past few months I've been rather distracted, and several things have 'gotten by' me. One of those things was comparing Robyn's DNA results with other Vosper cousins. Today I have finally gotten to it!
First, a disclaimer – I track in detail the DNA of 5 Vosper Cousins – myself, my 2 brothers, my 1st cousin Paula, and my 2nd cousin, Robert Vosper. If one of our Vosper Cousins does not match one of those 5 people I have no way to track their kit number, and they inadvertently may not be included in the results I show. I apologize if this has happened to you – I just have no way to track that many kit #s. If you have given me a kit # that does not show in the results below, and you'd like me to run the comparison, please re-send me your kit #....
OK! Now for Robyn's results…..First a summary of the positive matches:
As you can see by the results above, sorted by chromosome number and start position, Robyn matches a number of our cousins, though mostly in small segments. The exception is Bridget's DNA, where she has a large match. Among the interesting things I noticed is that Robyn MOSTLY matches people from the New York branch of the Vospers that I descend from. On the chart you'll notice that Bridget, Paula and Robyn all match on the 15th chromosome between 89.3 and 91.9 – a very nice 9 cM match!
Here are the details, direct from GEDMatch, person by person, with the positive matches first:
I get the "teeniest tiniest segment match award" for my match with Robyn:
Cousin Paula gets the "matches the most" award, with a total of 13 cM:
Cousin Bridget gets the "largest single segment" award, with 11.6 cM:
Cousin Berniece has 2 matching segments:
Cousin Barbara (on Lesley Dawson's line) also has a match:
Cousin Monica matches on 2 segments:
Cousin Robert has 1 matching segment:
Cousin Yvonne, also in Australia, has 3 segments:
The chart below summarizes the lines that match DNA graphically:
The remainder of the cousins I tested did not have any matching segments:
I hope this helps you, Robyn in seeing how your DNA proves our lineage chart. I would suggest that you add a name to your kit# -- I would suggest something like "Queensland Wms" or "Aus Wms" ….. something vague but suggestive….
If there are other Vosper Cousins out there who have DNA tested but have not downloaded to GedMatch, I hope you'll do so, so I can continue to document which segments come from which Vosper lineages. Please contact me if you need help, and I'll be happy to do what I can.
Lastly, if you have sent me something that I have not worked on, I apologize, and beg you to please send me a reminder. SO MANY things have scrolled off my email screens that it would take me forever to find them.
I have become a co-director of my local DNA Interest Group, which meets monthly, and I'm afraid that my attention has become too split….
Hoping you are all ready for the Christmas season, and that you'll give a little shout-out to our Jewish Vosper origins in some form this year…. I like to think that our mixed religious heritage makes us all feel 'inclusive' during this special time of year….I know I feel that way.
Cousin Teri
I was on gedmatch and comparing my kit to kits of Lynch descendants who have their kit numbers listed on WikiTree for https://www.wikitree.com/wiki/Lynch-2312 Lewis Henry Lynch of Virginia, USA.
ReplyDeleteI was wondering if the results I was gettign were true.
I was googling "is 6 centimorgans and 700 snp considered a true match". Your site was the first result.
It appears you may have New York lineage , so I'm wondering if that's the possible connection

Is this meaningful?
Hi, and thanks for commenting on my site.
DeleteThe issue of small segments is complicated, with most genetic genealogists believing that they are too unreliable to be used with assurance of validity. In the cases you see on this site, we know we have common ancestors, so the small segments MAY be indicative of a match.
Blaine Bettinger, in his Facebook group, "Genetic Genealogy Tips & Tricks" just did a very involved discussion of small segments that you will probably be interested in. You can find it here: https://thegeneticgenealogist.com/2017/12/29/a-small-segment-round-up/
In general, even when I'm looking at small segments I do not lower the SNPs below 500.
Do you have Vospers in your lineage?
