By 1851, she was maybe living in Livingston Co., NY. I had her husband's name as James Ammerman, but the will of Sarah's father gives his name as Thomas Ammerman.
From Ronny Bodine:
In the 1836 will of her father, Sarah is named as Sally, wife of Thomas Ammerman and in the 1851 probate of his estate she is named as a surviving child, Sally of Livingston County. In 1850, Mt. Morris, Livingston County, New York there is the family of James J. Ammerman 60 NJ farmer, Sarah 53 NY, George Vantyn 17 NY. George Vantyn was named as a grandson in the 1851 probate of Abraham Bodine's estate so it seems clear this is the correct family.
Note from Dave: I wonder if the James J. isn't really James T., the "T" being for "Thomas."
