I am looking for information regarding the descendents of Jacob Carl Pettit of Freedom, Dutchess County, New York. His wife was Hannah Johnston. His sons and daughters were Silas J. Pettit b1829, Robert W. Pettit b 1835, William Pettit b 1832 and Ann Earl Pettit b 1831. They were all born in New York. I am having trouble tracking them after the 1850 census where they are living in Palmyra, Wayne County, New York. I would welcome information or suggestions. I have seen this family listed as Pettitt sometimes.
