I know of 2 candidate families for your search. One is my own, desc. of Randall Pease (1783-1835) and Nancy UNK (1784-1853), who settled in Greenwood Twnshp, Steuben Co NY abt 1824. Their son Albert (1814-56) m. Lufanny Richie (1815-1882) and resided all his life in Greenwood. I have his descendants as well, and I feel certain that this isn't the family of your Edwin. The second family is that of Oliver Pease (1771-1863), who is considered to be the first settler of Troopsburgh, Steuben Co NY. His sons Oliver Perry Pease and Abram Pease moved across the PA border to Tioga Co. There is also mention of a son William, but I don't have any more info on this family. I've often wondered whether there is a close family connection between Oliver and Randall Pease, but I have been stumped. Good hunting.
