To whoever will read this:

Please help!! I am looking for any information about my grandfather's family line.His name was Josh Tom Mounce and he was born on Oct. 14 1922 in Ballinger Tx. He passed away Dec 6, 1999.His parents were Lottie Lee King(b.4/18/1895 d.5/1/76) and Josh Tom Mounce (b. 5/9/1893 d. 2/12/1967)Josh's name may have been Joshua Thomas.Although I can trace Lottie's family, I am unable to find anything about his family.Any information would be a great help.Thanks!
