One of my Dad’s cousins, Oscar Lee Hayes, was born Oscar Lee Richards. (I just found his birth certificate on Ancestry). When his Mother, my great-aunt Dolly, married Charles Raymond Hayes, either he was adopted by Charles Raymond Hayes, or just went by Hayes after that. Every record I have seen except his birth certificate he goes by the last name of Hayes. In the tree I am thinking I should put him by his birth name, and then under the “Also Known As” put Hayes.
