Hi Diane,
Welcome to the forum, and I can tell you right now that you've struck gold in coming here and finding Mark Tonner to help you find out more definate information about your father. He's amazing in how he comes up with tangible answers about things. He's been invaluable in his help to me in my own search for information about a special uncle in particular, but also others. Quite the education about lots of other information as well ... sounds like you're on a roll. Good stuff!
Good luck.
And Mark ... this for you from me just so's you know I don't forget
