Lemuel Mosher 1750-1831

I am trying to establish the parentage of Lemuel Mosher 1750-1831.He is supposed to be the son of Hugh Mosher and Sarah Davol but no docoumentation has been found to support this statement.He was from Dutchess Co., NY but was in Albany (now Putnam) County, NY in 1777, moved to Hillsdale, Columbia Co., NY the same year.Moved to Perinton, Monroe Co., NY in the mid-1810's where he died in 1831.Chamberlain &Clarenbach in their Mosher book list a son Lemuel b. ca 1750 for Hugh Mosher and Sarah Davol but no documentation is given.
