He is associated frequently in records with the names of the other sons. He joined the westward movement with the remainder of the family, but did not go beyond Washington County, Pennsylvania, where he resided in Strabane Township. His wife’s name was Catherine. His will1372, p. 173. As his authority, Farley cites Washington County wills, 4-157. was probated Oct. 31, 1826 in that county. Christian Hornish was one of the three men who were appointed to appraise his estate."

Researcher's Comment about Mosser Tombstone (1996):2228 "I have looked and looked for John Moser's date of death (i.e. his tombstone). I traipsed all over the area where he may have been buried - with a man who was copying cemeteries in the area. We never did come up with anything. I am sometimes inclined to think he was buried in a cemetery which may have been destroyed / removed when they built US Rt. 70 north of Washington, PA. In a preacher's diary (don't recall the preacher's name off hand), he mentions that he accompanied a man named Harnish to John Moser's three miles from the city where he preached in John Moser's barn. Harnish was related to John Moser in some way. Just now I cannot put my hands on the reference." [Note: John Moser was the brother of Christian Harnish's father-in-law Abraham Mosser.]
