Update to the Branch of Adam Brouwer Descendants on the YFull YTree

The branch of YFull's YTree which is populated by descendants of Adam Brouwer of Gowanus, L. I., and identified by the SNP E-Y19643 has been updated to include a new sub-branch. The updated tree is v7.04.01.

The new branch is identified by the SNP labeled E-BY52668. It is identified by the test results of two individuals. One tested individual can trace his lineage completely back to Adam Brouwer through Adam Brouwer's son Nicholas Brouwer. The second tested individual can be traced back to Charles H. Brower who was born in 1820, possibly in New York City, and died 12 January 1860 in Philadelphia, Pennsylvania. Although the YDNA testing of Charles H. Brower's descendant tells us without a doubt that he is a direct male descendant of Adam Brouwer, the ancestry of Charles H. Brower, beginning with the identity of his father, is still unknown. The identification of this SNP, which is only shared by these two tested descendants of Adam Brouwer, tells us that Charles H. Brower is very likely a descendant of Adam Brouwer's son, Nicholas Brouwer, who was born in 1672. Furthermore, we do have one other very likely descendant of Nicholas Brouwer on the YFull tree, and since this descendant does not share E-BY52668, it is very likely that the common ancestor of the two who do share E-BY52668 is somewhere among the male descendants of Adam Brouwer's son Nicholas Brouwer. In other words, Nicholas Brouwer himself did not have SNP E-BY52668, but it first appeared with one of his descendants who was born previous to 1820.

For a bit more on Charles H. Brower, see the post of November 8, 2018.

The Brewer DNA Project now has 15 members of the Adam Brouwer sub-group who have taken FTDNA's BigY test and have had their test results analyzed by YFull and placed on YFull's YTree. The Adam Brouwer sub-group of the Brewer DNA Project now has a total of 49 members, 26 of whom do know their complete ancestry back to Adam Brouwer. We would suspect that if more members could upgrade to the BigY test AND submit their results to YFull for further evaluation, we would likely be able to identify additional SNPs that will identify new sub-branches of Adam Brouwer's descendants. This in turn may help those who are yet to identify their complete ancestry back to Adam Brouwer to do so by narrowing down the possible lines of ancestry to consider. Those considering taking a BigY test should contact Hank Graham, the administrator of the Brewer DNA Project, with any questions.
