Jen,
I'm sorry I don't have your father or grandfather in my data, but I'm trying to get in touch with a lady, Sherry Miller. She has done a lot of reasearch on the LeMunyon family. The web site that I have for her is no good. I found another web address for her http://www.oocities.com/~turberville/ and I've sent her an e-mail, I'll let you know if I find something. Do not give up.
Nancy
