Item no. 6 in Part 1 of the abstracts of miscellaneous Monmouth County Court Papers pertaining to Brewers and Browers, is an agreement witnessed by Sylvanus Brewer. The agreement dated 2 April 1800, appears to be in regard to a debt owed by Hendrick Van Brunt and Anthony Holmes to Sarah Bacon. Sylvanus Brewer was simply a witness to the paper.
There is nothing that could be considered as genealogical evidence in this document, but it is most likely that this Sylvanus Brewer (there were not many Brewers by that name) was the one baptized 21 June 1767, recorded in the records of the Dutch Congregations at Freehold and Middletown. His parents were Hendrick Brouwer/Brewer and Abigeltie Hunt. Sylvanus is a descendant of Jan Brouwer of Flatlands, Long Island.
Sylvanus was married to Idah West, probably around 1790 or so, and they had nine children. He died in 1820, and administration on his estate was granted to William Truax. According to an unpublished manuscript titled, "Outline Genealogy of Lorenzo D. Brewer of Hunterdon Co., New Jersey," Sylvanus Brewer "owned a farm of about thirty acres near Swimming River Bridge, near the small town of Freehold." Lorenzo D(ow) Brewer was a grandson of Sylvanus Brewer.
