I was adopted may 5, 1976 and born July 18, 1973 in lansing, my. I know my adoption records were sealed by my birth mother and am not sure of my biological last name(my adopted mom said she thinks its Frizell but I'm not sure as to the spelling). I have 3 biological siblings and my birth certificate gives my adopted parents as my biological parents and that's about all I know. Any helpful hints to find them?
