I have a lease dated ca. 1796, that granted Pottagh to Charles Wilson. His son, also Charles Wilson, is mentioned in the OS Memoirs as emigrating to Philadelphia ca 1834, age 25. He went from Philadelphia to Mauch Chunk or Summit Hill, Carbon Co., PA There he m. Martha McLean who may have been connected with the McLeans of Farrenlester. He d. 1852 in Port Richmond, which is now part of Philadelphia. Martha m(2), John Lyle, son of Rev. Wm Lyle of the First Dunboe and moved to Adams Co., IL. I think the John Wilson who m. Sarah Jane Hazlett was a son of a John Wilson, who may have been the one you mention. There was a Charles Wilson in Maddybenny, Agherton in 1831, and I've thought he may have been connected with Pottagh. - Dan
