I have found info on this in the Bickford Newsletter produced by Mahlon Bickford. He can be reached at MCBICKFORD@aol.com. What I have says that Abijah Bickford born Jun 8, 1770 married Sarah Cressey, born April 26, 1779. The newsletter says that Abijah was residing in West Pond Plantation, ME (later Dearborn, now Belgrade) as of 1790. I think Mahlon will have more info.
