I am a Springstead from Onondaga Co. My g.g.g. grandfather's name was Henry, b. 1799 d. 1854 m. Amanda VanCamp, b. 1802 d. 1856. There were 10 children: William, Mary, Austin, Albert, Albert, Cornelia, George, Grove, Julia and I haven't figured out who last one is yet. How are you linked to Onondaga Co.? Don't know if I can help, but would like to try.
