No. 36, Mary Gifford, Heir of Isaac Brewer
In this document, Mary Gifford, of Howell Twp., Monmouth Co., New Jersey, grants power of attorney to Joseph W. Fleming. The document is dated 3 March 1836. Mary Gifford, states that she is the "mother, and only surviving lawful heir of Isaac Brewer, deceased, of the city and county of Philadelphia, in the State of Pennsylvania, who died in the County of Monmouth, State of New Jersey in February 1834." Mary Gifford is appointing Joseph W. Fleming, of Monmouth Co., to handle the settlement of Isaac Brewer's estate.
The principals here, Mary Gifford and Isaac Brewer, have not been identified and they do not appear in the Brouwer Genealogy Database. The information provided above, by Mary Gifford, tells us that she is the mother of Isaac Brewer who died in 1834 in Philadelphia. She describes herself as his only lawful heir which tells us that Isaac was not married (or was a widower), and had no living children of his own. It can also be deduced from Mary's description, that she was married to a man named Brewer (Isaac's father), and was afterwards married to a man name Gifford (the name she is using in the document).
With the information above, I am first led to the family of David Brewer (1758-1804) and Ann Morris, of Monmouth County, New Jersey. Among their children is a son named Isaac (died before 1816, whose wife's name is said to be Margaret), and a daughter Elizabeth, who was married to Annamiah Gifford. The family lived in Monmouth County, New Jersey. David Brewer is a grandson of Adam Brewer (1696-1768/69) and Deborah Allen of Monmouth County, and a descendant of Adam Brouwer of Gowanus, Long Island. I suspect that when, or if, Isaac Brewer who died in 1834 in Philadelphia, and his mother, Mary Gifford, are identified, they will find their place to be among the descendants of Adam Brewer and Deborah Allen.
