Quick links to individuals whose ancestry has yet to be determined.
- Abraham Brewer He married Eunice Griswold and lived at Chemung, Tioga Co., New York. A descendant has participated in the Brewer DNA Project (kit no.109921) and the results indicate that Abraham is NOT descended from either Adam Brouwer or Jan Brouwer. The descendant's R1a1 haplogroup is similar to only one other participant in the Project. The testing of more descendants may be helpful.
- David Brewer Found on the 1810 census in Kortright, Delaware Co., NY. First thought is that he belongs to the family of Elias Brower & Phebe Lucas, but as of yet I have not identified where.
- Derrick Brewer In 1899, Jacob Jennings Warner Brewer stated that Derrick Brewer was his great-grandfather. As Jacob demonstrated in his own written and spoken words that he had more than a passing interest in his family history, there is no reason to doubt that he knew his great-grandfather's name, even if he did not know him personally. By backtracking, Derrick's birth can be determined to have been prior to 1735, probably in the decade of 1725-35. His surname may have been recorded as Brouwer, Brower or Bruer. My virtue of his given name, Derrick (Derck, Dirck, Richard) it is highly probable that Derrick descends from Jan Brouwer of Flatlands. A possibility as to his identity is offered on his profile page, but this is not yet certain and further evidence is sought.
- Henry Brewer Brewer DNA Project, kit no. 32813. A descendant of Adam Brouwer, he is referred to as Heinrich Bruer by a direct descendant. (He may well have been born as Hendrick Brouwer). The DNA results indicate that he is closely related to Peter Brewer (below). Henry, or Heinrich, and his descendants are found and appear to have remained in Westmoreland County, Pennsylvania throughout the 1800's.
- Jacob Brower/Brewer (1757-1818) He came to Digby, Nova Scotia from the New York City area in about 1783 and there married Elizabeth Van Tassel. A Christian Brower is found in Digby at the same time, but if there is a relationship between the two, it has not yet been discovered.
- Jacob W. Brower (1812-1868) from Randolph Co., NC, went to Surry Co., NC where he was a wealthy miller and manufacturer. As his origins are in Randolph Co., he may be a descendant of Hubert Brower who did have descendants relocate to Randolph Co. in the very early 1800s.
- Jannetje Brouwer Married Cornelius Tunison in 1749, she was living in Feb. 1790 when he wrote his will. Some possibilities are mentioned in her profile.
- Jeremiah Brouwer He married Anna Elsworth with a N.Y. lic. dated 28 Dec. 1763. He was therefore likely to have been born between 1733 and 1743. His name, Jeremiah, would strongly suggest that he was a descendant of Adam Brouwer through either his son Abraham or son Nicholas. Little has been found regarding Jeremiah and his wife Anna Elsworth, and no record of any children has been found.
- Jeremiah John Brower Brewer DNA Project, kit no.107708. Jeremiah John Brower is a descendant of Adam Brouwer, and by virtue of his name, Jeremiah, most probably descended through either Adam's son Abraham or son Nicholas. Born in 1815, in New York, Jeremiah John Brower is first found in Cass County, Indiana and lived for much of his life in Jackson Twp., Lucas Co., Iowa. It is suspected that his father was a John Brower who is found in Cass County, IN in 1840.
- Job Brower He appears on the 1800 U.S. census in Hempstead, Queens Co., New York, aged 26-44, among other Browers/Brewers who are sons of John Brower and Hannah Abrams. Job, however, is not a member of this family.
- John Brewer (d.1809 in Ohio) DNA testing of descendants has confirmed that John is a descendant of Jan Brouwer of Flatlands and he was one of the subjects of the October 2007, NYG&BR article, "DNA Analysis: Adam Brouwer Berckhoven, Elias Brewer and John Brewer." However, John's immediate ancestry is still not known.
- John Brewer (1730-1821). He served during the Revolution, suppossedly in Tryon County and is buried in Riverside Cemetery, Chemung, NY, as is Abraham Brewer who appears above.
- John J. Brewer John J. Brewer, born in New Jersey, married Elizabeth (possibly Waters, or possibly Britton). They began their family in New Jersey and moved to Williamson, Wayne Co., New York in about 1830. John J. Brewer is a descendant of Jan Brouwer of Flatlands, as shown by DNA testing of descendants, however, his immediate ancestry is still not known.
- John Rose Brewer DNA Project, kit nos. 7689, 9135, 8068, 67034, 64319, 99500. John Rose is first believed to be found in Rockingham Co., Virginia (east Pa.'s southern border) and finally in Ohio. Test results from his descendants do not match those of any other Rose families, although they do show a close relationship to the descendents of John Brewer (above). The Brewer - Rose connection is yet to be discovered.
- Margarita Brouwer She was married to Lodewyk (Ludwig) Bomper and was a member of the New York Dutch Reformed Church in 1748, with children baptized there 1749 to 1753. A son was baptized in the First Moravian Church of NYC in 1759. Thus far no evidence has been found that would place her as a descendant of either Adam Brouwer, Jan Brouwer, or Willem Brouwer.
- Mark Brewer Probably born between 1760 and 1765, he is found in Hardin County, Kentucky in 1810, 1820 and 1830, but is not likely a brother of Samuel and Peter Brewer (below) who are also found in Hardin Co. in 1810.
- Peter Brewer Brewer DNA Project, kit no. 28193. Certainly a descendant of Adam Brouwer (more probably through Adam's son Pieter). Peter Brewer appears to have been born in the decade of 1750-1760, possibly in Sussex County, New Jersey. He is found in Westmoreland Co., Pa. in the late 1780's and finally in Hardin Co., Kentucky. He apparently had a brother Samuel (below).
- Peter Brewer Claimed to have been born in 1740, he married Elizabeth Stone, and left descendants in Greene Co., NY, Allegheny Co., NY, and Michigan. Peter had previously been considered, by some, to have been a son of Johannes Brouwer (a descendant of Adam Brouwer) & Elizabeth Concklin. Recent DNA testing of a descendant, however, demonstrates that Peter CANNOT descended from Adam Brouwer.
- Peter Brewer (d.1836) Peter Brewer, of Easton, Washington Co.,NY applied for a pension for his service during the Revolution at which time he lived at Cortlandt, Westchester Co., NY. He moved to Washington Co. and is found there in 1800, and died 6 Feb 1836. The date of his birth, name of his wife, and placement among one of the known Brouwer families, has not yet been discovered.
- Peter Brewer Found on the 1840 census in Davenport, Delaware Co., New York. Possibly a member of the Elias Brower & Phebe Lucas family?
- Samuel Brewer A brother of Peter Brewer (above). He lived in Hardin and then Mercer County, Kentucky after the Revolution. Samuel and Peter are likely to be closly related to Henry Brewer of Westmoreland Co., Pa., and all three are descendants of Adam Brouwer. The link to Adam has not yet been found.
- Stephen Brewer Born ca. 1772, married Mary Whitsett and settled in Grant Co., Indiana. A descendant has participated in the Brewer DNA Project (kit no. 80836) demonstrating a descent from Jan Brouwer of Flatlands and a close relationship to the descendants of John Brewer (d.1809) (see above).
- William Brewer Brewer DNA Project, kit no. 46637. A descendant of Adam Brouwer. Also seen as William Bruer, he is found in Southwark, Philadelphia in the first half of the 1800's. His age, given as 73 in 1850, is probably overstated and he was more likely born in the decade of the 1790's. His grandson Joseph Brower left Philadelphia for Birmingham, Alabama in the late 1880's. DNA test results indicate that he is most closely related to Peter Brewer, and Henry Brewer (above).
