I just found this site recently and would like to add my family information.
I am related to the Adair family through my mother's side of the family. The first Adair I have so far is a Henry Adair who was born 27 Feb 1809 in New Jersey. He married a Mary Van Tuyle (I have no date of marriage) who was born 19 July 1815, I think in New Jersey. According to an 1850 New York census the couple had seven (7) children; Isaac 17 yrs, Margareth 15 yrs, Elijah 11 yrs, Mary J. 9 yrs, Henry 6 yrs, Nelson 5 yrs and George 2 yrs old. Mary's parents, Isaac Van Tuyle and Maria lived witht he couple also.
My side of the family comes from Nelson Van Tuyle Adair, born 15 Feb 1846 in Varick, New York. Nelson married Mary Randolph (no marriage date). A son, Harry Randolph Adair was born 20 Dec 1869 in Owosso, Shiawassee County, Michigan. He married Neva Esther Smith 1 April 1895 in Big Rapids, Mecosta County, Michigan. The couple had three daughters, one of whom is my mother.
I would like to connect with any relatives who are also working on this family and of course I would love to push back the family time line as far as possible.
