I'm looking for a John DeYoung. I found out at the age of 30 that he was my biological father. I know that he lived in Oak Lawn, IL in the 60's. He was about 21 or 22 in 1966 (year I was born) Also know that he's been married a couple of times and as far as i've been told never had any other children. Just wondering who he is and what he looks like. Every older man I see on the street I wonder if he's my dad. If anyone's out there that knows him, please let me know or let him know I'm looking.
