My grandmother, Nellie Snyder Sawdey (1866-1927), appears pretty certainly as the daughter of Thomas and Christianna Snyder of Groveland, New York. However, I'm having trouble finding out Thomas's parents--possibly Cornelius Snyder and Prudence Bailey, but I cannot confirm this. Also, I have not been able to determine Christianna's maiden name. My father thought it was Kelly, but the only Christianna Kelly I can find appears in the same 1850 census that lists Thomas and Christianna as married with a child. Has anyone got any leads on these questions? Thanks!
