I am seeking the parentage and ancestry of my great-great grandmother Mary Emeline Purdy. She was born in Westchester Co. New York 15 Nov 1820, married John Tremper Jr. 25 Jan 1845, Greeenbush Presbyterian Church, Rockland Co. New York, died 25 Jan 1851 Rockland Co., buried Oak Hill Cemetery, Nyack, Rockland Co. New York. One of her sons, my great grandfather, was named Hiram Purdy Tremper.
I think her father may have been John E. Purdy b. 1779, living in Clarkstown, Rockland Co. in 1860 and her brother Hiram Purdy b. 1816, but I am not sure. There are of course MANY people named Purdy in Westchester County at that time.
