June 14, 1982 Looking for brother

My name is Cheri(21), and I recently found out about 4 years ago from my father that I have another brother. When finding out I started searching on the net and found that my mom had been also trying to look for him, and so I thought I would join the search. She does not know my sister(23) or my brother(18), and I know about this older brother of ours, and I think it would be wonderful to find him. The only information I know is that he was born in Portland, Or and his birthday is June 14, 1982. My mothers name is Yvonne L. and my dads is Dale C., if that helps. Please if you have any response it would be great!
