Adam Brouwer Descendants on the New YFull YTree v5.06

YFull has released their latest version of the YTree, this version being v5.06. Although no new branches have been identified, there are now seven members of the Adam Brouwer sub-group of the Brewer DNA Project who appear on the tree. This branch (subclade) of the YTree has been identified by YFull using the terminal SNP E-Y19643. The subclade is online here. YFull lists 17 additional SNPs that are unique to the subclade (18 total SNPs). The 18 are E-Y19643, E-Y19644, E-Y19645, E-BY6342/E-Y12019, E-Y12120, E-Y20121, E-Y20122, E-Y20123, E-Y20124, E-Y20125, E-Y20126, E-Y20127, E-A9482, E-A9483, E-A9484, E-A9486, E-A9487, E-A9488.

In addition, two of our members are identified as a sub-branch (subclade) of E-Y19643. They are identified by the terminal SNP E-BY6245. While the two share the above SNPs with those who are identified by E-Y19643 (etc.), the SNP E-BY6245 is unique to them and so sets the two off as a subclade. The two members are known to be first cousins, and therefore this common identifying SNP would have to have first appeared somewhere in their paternal ancestry between their grandfather who lived during the first half of the twentieth century and Adam Brouwer. But just where in that line, cannot be learned from the present data.

All members of this subclade are descendants of Adam Brouwer who was born at Cologne (a city in modern day Germany) sometime during the decade of 1610 to 1620. He served in Brazil as a soldier employed by the Dutch West India Company (WIC) in the early 1640s, and went from there to New Amsterdam probably in 1644. Adam Brouwer settled at Gowanus on the western edge of Long Island (now a neighborhood in the borough of Brooklyn in New York City) where he died in early 1692. His seven sons all left descendants. Adam Brouwer's ancestry, and the names of his parents, is not known.

Most of our members represented in the current YTree cannot (as of this writing) cannot identify their complete paternal lineage back to Adam Brouwer. However, we do know that they are descendants of Adam Brouwer based upon the results of Y-DNA STR marker tests comparing them to members who do know their complete paternal line back to Adam Brouwer. The seven who are found in the current YTree v5.06 represent the following Earliest Known paternal Ancestors (EKA):

YF10565 = Benjamin Brewer (1796-1885, PA, IN, m. Elizabeth Rony)
YF10057 = John Brewer (1796-1849, Broadalbin, NY, m. Elsie Mosher)
YF08704 = Benjamin Brewer (1755-1834, PA, KY, IN, m. Catherine Mellinger)
YF04988 = John G. Brewer (1795-1886, Greene Co. OH, m. Sarah Miller)
YF03732 = Adam Brouwer through his son Abraham Brouwer
YF08703 = Peter Brewer (1750s-1840/41, Hardin Co., KY from PA, m. Margaret Hobach)
YF05152 = Peter Brewer (1750s-1840/41, Hardin Co., KY from PA, m. Margaret Hobach)
(Nos. 6 and 7 represent the subclade E-BY6245 mentioned above and are first cousins)

Currently in the works are four additional members who are awaiting results and/or analysis. Of the four, two are descendants of Adam Brouwer's son Nicholas Brouwer, one is a descendant of Adam Brouwer's son Jacob Brouwer, and the fourth is a descendant of Mathew Brower/Brewer of Greene Co., Pennsylvania whose ancestry back to Adam remains unknown. With any luck the results and analysis of these four tests will be up online by the end of the year. The Project seeks additional descendants for testing.

The Y-DNA test used here is the Big-Y which is offered by Family Tree DNA (FTDNA). Analysis of the test results and placement on the YFull YTree is done by the company YFull which is independent of FTDNA. Current members and those interested in becoming new members are welcome to contact the administrators of the Brewer DNA Project for information on testing.

    Elizabeth Rony (or Roney) who married Benjamin Brewer (1796-1885) is the granddaughter of Catherine Mellinger & Benjamin Brewer (YF08704). Elizabeth's parents were James Roney & Margaret Brewer.

    Her husband Benjamin (YF10565) appears to be the son of Jane Hurdlee/Hurdley and of Henry Brewer (b. ca. 1750)-See "Another Henry Brewer of Western Pennsylvania" (http://brouwergenealogy.blogspot.com/2013/12/another-henry-brewer-of-western.html) which discusses the link between Henry and Benjamin-YF08704.
