10:10– Welcome, Reports and New Introductions
Loraine Financial Report. $66 as of April Meeting-took in $125. Paid Nancy back for the cost ($115) of the church-$50.
Now have $75 on hand. Would like to have $100 on hand to be able to buy a book or two periodically for the library since we use that space for free. A basket is on hand for your loose change.
Nancy explained how to change the kits she provides to be under your name.
New attendees introduced themselves. Seven people offered up info as first-time attendees
34 People in attendance
10:30 Q&A Autosomal DNA
12 Marker y-DNA only on provided test-David F. helped her with the answer
No other questions on Autosomal DNA

Sharing-wanted to do a Y-DNA but both men in her family said no. If someone is paranoid, they shouldn’t test. Y-DNA changes so little that it will not bring up any illegitimate kids
Transfer to FTDNA–You need to do that. The process is on the website. Transfer the ones that are most important. Then you will get a link that you can share and if you unlock four others your goes for free.
If the first match is 65 centimorgans, then it is like a second cousin once removed
You can’t transfer the results from 23& Me because they changed their chip. Ancestry is changing their chip… that is the gossip out there. The same company makes all the chips; different services look at different parts.
Conference in Augusta: It was progressive, and a little over a few folks experience level.
Other Meetings: Conference next week in Portland with Josh Taylor
Nancy showed a short YouTube Video explaining cousin relationships
Your best bet for organizing your matches as a spreadsheet
Nancy did a short little intro to Y-DNA
It is the Male line directly through the paternal surname line
Markers are locations on a chromosome. The more markers the better. 37 plus is needed. The more the better. 12 marker test will give you the haplogroup.
On a 37 marker test, 0-3 mismatches is the max if you are related. If you go up to a 67 marker test then you can have up to 6 mismatches.
Success story-Mason/Heath question in her family. At 12 markers the Heath surname was evident.
11:15 Presentation: Fun with Y-DNA -David Farnham
Nancy introduced David Farnham
Hallmark of a good teacher is to inspire others to learn on their own. Nancy had done that for them
Autosomal is good for a few generations-4-7 max
Y-DNA can be used to confirm the genealogical record of the paternal line
Y-DNA is Paternal Line
It goes backs hundreds of years almost unchanged
Terms you have to know.
22 Pairs and 1 pair of sex chromosomes
Two ways to Process DNA
STR-Stutters in the DNA ( the same letters are repeated) values usually in the 5-50 range. Useful in genealogy. It is predictive of haplogroup (deep ancestry)
SNP single nucleotide polymorphism shows Deep Ancestry.
Thirty-seven markers are good, sixty-seven is better, but you might need an 111 marker test if your line is daughtered out.
For each marker, there is a Code of letters and their values.
Most of the services are using the same STRs and in the same order.
Dave did 111 and got four matches…2 at 12 markers which is okay but not helpful
1 at 25 markers and 1 at 67.
There is a tool on FTDNA has a predictor tool for the Y-DNA. It predicts what generation you most likely share a common ancestor. The use very conservative factors so the estimates low.
There are also Surname Projects- They show genetic distance — how how many numbers are different and by how many numbers (total) So there can be two stutters, one with 1 & one with 2 for a total of 3.
There are also Haplotype Projects-these are different things (SNP’s) that are being looked at.
There is Y-Search that allows you to upload Y-DNA from other sites. It is not part of FTDNA, but they run it.
When the genealogical record is compared, it is possible to see where the people who match you “branch” off.
You can see the earliest possible time of a mutation happening but not when it did.
Use yDNA to discover the family in England-so far a project in the works. The Ralph & Alice Farnham family is the largest group in the US.
When looking at the deep Y-DNA
AtDNA admixture (Voodoo)
Ancestry, NatGEO and FTDAN transfer-tested various times ranged 59-75% for his English origins
AncestrybyDNA- 16 points STR test predicted haplogroup G2a
Third party transfer to NEVGAN Predicted haplogroup ais G2a2a (G-L91)
Surprise!! Expected haplogroup was R1b (for UK) and G2a is from Sicily!
FTDNA came back with haplogroup G
Nat Geo test (it is a snip test) Confirmed G2a2a1a2a1a (G-FGCC5672)
Haplogroup G is the group who waited for the Ice Age to end before migrating to Europe (9K-6K ago) It is uncommon north of the Mediterranean.
You can not match on the STR’s but match on the Haplogroup. David is a match for Otzi the Iceman, who was killed in the Alps around of 3100 BC.
STR Tests -FTDNA is the gold standard. Do at least 37 or 67 unless you have a unique situation. You can do additional testing also
SNP tests are more for research and deep ancestry
Y-DNA useful for the paternal line only looks further back, can prove the gen. record, discover new relationships and more points the better.
Deep Ancestry-Geno 2.0 Nat Geo offers the best bang for the buck.
The ISOOG.org wiki has the most accurate info and helpful sites.
Codis uses STR tests but they test other stuff than the Genealogical tests.
Confirmed Haplogroup column for additional testing is not worth the money.
Genetic Distance-how accurate is it. The chart provided shows an estimate of how often the stutter is going to happen. It is not specific enough at 67 marker test.
