Looking for adopted brother James??

Looking for adopted brother James who was born in michigan around 1964. Birth name was James Joseph Cates or James Joseph Reid, because she wasn't married to our dad yet and i believe her family put her in an unwed mothers home to have the baby and put up for adoption. James has two younger brothers and one sister, that would be me. I have your birthcertificate and just started to look for you so I hope you are well and happy and willing to meet your three siblings. Lots of love kelly
