Looking for Armitage Family Ohio OR Michigan

Hi. I was adopted at a very young age. I don't know much about my biological family but I need answers and the family I do know can't give me much help. I do know I was born August 5th 1980 In OH. To Rick l. Armitage Sr. And his wife's name was Carla Owens. My Aunt Pamela Joyce Armitage and husband Don L McQuillin. They had adopted both me and my little brother .
I don't really know where to start so I am hoping someone can GI e me some insite
