Over the course of time I have found very few references to persons named BREWER or BROWER in Richmond County (Staten Island), New York. There are mentions of two Brewers in the probate records at the Surrogate's Court at St. George, Staten Island. Abstracts can be found in a typescript titled, "Wills of Richmond County, N. Y., 1787-1863, originals on file Surrogate's Office, St. George, Staten Island, New York," compiled by Frances S. Fast in 1941. A copy of the pages pertaining to Brewers taken from this typescript was included in William B. Bogardus' collection, and it is now online:
Wills of Richmond County, N. Y. by Frances S. Fast
The first mention is in the will of Ann Robbins, widow of Robert Robbins of New York City, deceased. Ann's will was dated 29 August 1844 and proved 18 September 1847. She died on 30 September 1846. In her will she leaves her property at Castleton and Southfield (both on Staten Island) to her daughter, Christiana Ann, the wife of Benjamin P. Brewer. In addition, Benjamin P. Brewer is appointed as the only executor of the estate. The probate hearings record (among others) the children of Benjamin P. Brewer and Christiana Ann, naming them as Daniel R. Brewer (of age), Benjamin, Robert, Ann, Caroline, Andrew J. and John N. Brewer. This Benjamin P. Brewer would be Benjamin Prince Brower, born 2 May 1801, son Nicholas Birdsall Brower and Ruth Prince. Benjamin is a descendant of Adam Brouwer. n 1860 he was Post Master of the the New Brighton Office on Staten Island.
The second mention is the will of Samuel Brewer who died 3 December 1861 at Westfield, Staten Island. His will is dated 25 September 1861 and was proved 12 February 1862. He leaves his estate to a Sarah Carlock "as long as she stays unmarried." On her death or remarriage, the estate is to go to the children of his brother, Hastings Brewer, except a watch, which is to go to Abraham Riker Kelsey. The probate hearing also records sister (sisters?), Mary Eltting, Hannah Smith, Maria Mayhew, Eliza Edwards, Sarah Brewer, and sons of Thomas Brewer, deceased, names unknown, and brothers Hastings Brewer, Henry and William. Determining just who this Samuel Brewer was took a little digging, which started with finding Sarah Carlock on the 1860 census. She was age 55, living in Westfield, Richmond Co., New York, as a housekeeper in the home of "James" Brewer, age 64, born in England. Perhaps James was a brother of Samuel, or perhaps he is Samuel with his name erroneously recorded as "James." In 1850, Sarah Carlock, age 45, was living with Samuel Brewer, age 59, born in England, in Ward 12, New York City, New York. In the household was a Mary Brewer, age 61, and adults John Carlock, James Carlock, George Carlock and Henry Carlock. In searching for Hastings Brewer, the only one found, was living in 1860 in Southfield, Berkshire Co., Massachusetts. He was age 49, born in England. This Hastings Brewer had married Fedilia Bunnell on 11 September 1842 at Harwinton, Connecticut. The 1860 census includes, Fedilia and six children aged 4 to 16 years. The family can be found at New Marlborough, Berkshire County, Massachusetts in 1850, 1870 and 1880. Hastings Brewer's death is recorded in the New Marlborough Town Records, the date being 27 December 1890. So, it appears that the Samuel Brewer who left a will in Richmond County, New York, was an immigrant to the U. S. from England sometime during the first half of the 1800s. He was not a descendant of either Adam Brouwer of Gowanus or of Jan Brouwer of Flatlands. Likewise, the Hastings Brewer of Berkshire County, Massachusetts, is not a descendant of one of the New England Brewer families who are found that county throughout the 1800s. As for Sarah Carlock, she apparently was a widow prior to 1850. In 1880 she is found enumerated as "mother" in the household of Robert Carlock, age 53, blacksmith, in New York City.
