Thank you for your interest in trying to help me. It did take me a while to get the info I already have, and sadly, I really don't think I will have much luck in finding out the rest without full names and some kind of date.
I may be able to if I were to find an original birth record of my grandfather on which his parents names might be recorded. I don't write in Farsi and really don't know what kind of system they have in Tabriz where I may write or inquire. I won't give up, though. None of his parents' names where listed on Immigration papers, or Natralization papers. So, I will post on some different forums about how I should proceed. Again, thank you. Toni
