DNA Group 6 Analysis
Essex and Suffolk Counties, England
FFA Charts #1, #2, and #3

This page updated by Mara French on 11/17/10. Send any corrections or additions to this chart to Revisions: 2010. The nearby cities where various French families lived are: Halstead, Sible Hedingham, Great Maplestead, Twinstead, Assington, Great Tey, Gosfield, Stisted, Greenstead Green (Greenstreet), Arkesden (west of Great Bardfield), Wethersfield, Great Bardfield (Pitney Manor), and Finchingfield. The Stour River at the top-right divides Essex from Suffolk county; therefore, Assington and Bures St. Mary are the only towns in Suffolk for this analysis. Stanstead Hall is to the right of Greenstead Green.

Clarification of the DNA Tests

BEWARE. ALL THE INFORMATION ON THIS PAGE IS SUBJECT TO MORE VERIFICATION. PLEASE DO NOT TAKE ANY OF IT FOR GRANTED. We may never know the real ancestry for sure, as the records do not go back any further, but I did my best at deciphering them. Mara

For Group 6, there are 4 testers, and of the 25 tests each has taken, only 2 numbers are off 1 point. In other words, 23 of the 25 tests taken match exactly. Please refer to the test results for Group 6. According to the Frequently Asked Questions (FAQ) presented by the Family Tree DNA, under the title “Probability for Most Recent Common Ancestor (MRCA), if 23 or 25 tests match, there is 50% probability that the MRCA was no longer than 11 generations ago, and 90% probability that the MRCA was no longer than 23 generations ago, and 95% probability that the MRCA was no longer than 27 generations ago. We go back 18 generations.

These are the Charts involved for DNA Group 6 Ancestry, all of whom immigrated to New England during the Puritan Migration ca. 1630-1637:

Jacob French, b. ca. 1553, FFA Chart #E1.
William French, chr. 1606, FFA Chart #E2.
John French, chr. 1599, FFA Chart #E3.

The 5th generation is approximately when the Puritan Migration to the Colonies occurred about 1635. These immigrants were born during the very early 1600s. Most descendants of these Puritans living today are in the 16th or 17th generation, if the generations are calculated more or less as follows:

1. 1504
2. 1525
4. 1584
1608 Puritan ancestor generation (those who immigrated to New England)
7. 1673
9. 1735
11. 1780
13. 1850
15. 1913
17. 1965

You should test more markers when you want to compare additional markers against others with similar results to you. The additional STR markers will refine your matches. If you currently have many Y-DNA12, Y-DNA25, or Y-DNA37 matches you should certainly consider upgrading your Y-DNA profile to a higher level. You may always upgrade to a higher level of testing as your number of matches and needs change. You need not retest because you first test is kept for possible later testing. Our motto could be: Test only what you need, and upgrade only when necessary.

Pedigree Chart of DNA Group 6 Ancestry

This Pedigree Chart combines FFA Charts #E1, #E2, #E3. Starting in 1985 and onwards, these charts were kept separate; then, due to DNA testing, we were able to combine them – that and with a lot of research into parish registers in Essex and Suffolk, England. These charts will still be kept separate due to their enormous size, plus to keep them more small-family oriented.

Considering the first 25 markers of the DNA test results between Thomas of Chart #1 and William of Chart #2, there is only 1 marker different that that marker is only 1 number off; therefore, there are 24 of 25 markers which gives a 90% probability that the MRCA was no longer than 16 generations ago, or a 95% probability that the MRCA was no longer than 20 generations ago, the connection of which this chart shows below.
