Sorry it took so long to get back to you.We know that John Miles, John Rupert and Mary Elizabeth Walker have died. We would really like to find out if David John is still alive.He was listed as living at 2430"C" St., Apt. C, San Diego, Ca. in 1968.We live in NOrth Carolina and we simply can't afford to make all those phone calls.I don't even know if David knows that he has a nephew(my husband). We would love to see a pic of David's father, John Rupert. My husband has never even seen a picture of his grandfather.
