Thank you so much! After very careful researching of birth dates, I believe that I have the wrong father.
My husband's relative is Henry P. Schermerhorn, who married Sally Elizabeth Ackley from Milford, NY. They were listed as living in Laurens, NY in 1850 and I've found other documents showing that he and his young family moved to Union, IA and that he was a blacksmith by trade. I cannot find his father, which would link him to the Schodack Schermerhorns.
