This is a follow-up to the earlier posts on the Y-DNA
haplogroups for Willem Adriaense Bennet (WAB), which were generic.
Since that time, eight descendants of WAB have upgraded to an extensive,
full chromosome Y-DNA paternity test called BigY-700. Data processing
alone for this test takes over 8 weeks, but the result is a sufficiently
detailed list of individual mutations, which occur every 50 to 100
years on average, such that the software is able to create a biological
family tree (called a TimeTree), showing the birth years of each common
ancestor between branches.
The unique haplogroup (branch name) for
WAB is E-FTB90013 (est. birth 1626, historical ~1605), which includes
him, his two sons, and their descendants. His older son, Adrian
Willemsen's haplogroup is E-FTB92022 (est. birth 1651, historical 1637).
His great-grandson, Isaac Adrianson's haplogroup is E-FTD68674 (est.
birth 1708, historical 1717).
This haplotree corroborates the WAB
family tree on this site with the corrections published by Morrissey, et.al. in 2017, but does not match the original 1962 tree published by
Ledley and subsequently by Kenneth Bennett.
The Y-DNA tree is
skeletal due to the small number of descendants. Luckily we have four
descendants from each of WAB's two sons, but only three of the eight
grandsons documented here are represented. Additional male descendants
are needed to fully corroborate the historical records family tree.
Please contact FTDNA directly to order this test or contact me directly with questions. The test is a bit
expensive, but the beauty is that nothing more is required of the
participants except their DNA. The analysis will automatically connect
you to all other Bennetts and other surnames (including Brouwer) who
have ever taken this test.
Bennets/Bennetts interested in participating in the Bennett Y-DNA Project at FamilyTreeDNA should contact the Project directly via their website, and/or contact Ron Bennett directly.
