A little more info might help us help you. If you look on your birth cert. it should tell your father's age and place of birth. You could then go to the place of his birth for his birth cert. and find his parent's names. You might also want to try a search online in the yellow pages for the state of your birth or his, for his name. My Great Great Grandmother was a Casto from Jackson Co WV. She married and they moved to East Liverpool Ohio. That is where I am from. You can email me direct at
