I think I might have found some information on your grandfather. I remeber I talked to you a while ago and hadn't found anything out myself. Recently I wrote a social security office and I got informaton about where my grandpa was from and his parents names.Anyways,I was looking in ANCESTRY.COM and found a record of War registrations and found a Gust Alex of Colorado. Said his relatives were in Greece. I also had found my Alexiou's(later Allex) went to CO. too. Hope this will help you a little. I'm sure if you go to ANCESTRY.COM you will find more info.
