I am also a direct decendant from John Clark Musser through their son Alpha, Rhodell (my grandpa), Roddy (my dad). We talked to Rhodell before he died and found out about Alpha but he did not know much about John Clark. I found the names of John's parents. They are John (born in 1795) and Elizabeth from the LDS website. John was born in PA. I hope this helps because I am trying to find out more about John Clark and John. It would be really cool if we could find out who the parents of John and/or Elizabeth were. They would probably be revolutionary war era folks.
