Hello
I can help you out if the child was born in Utah, but you can contact quite a few free/low fee searchers for CA that can give you the adopted name from the CA birth index. Which has been shut down, but most of the searchers copied it....let me give you a start point with a friend/bmom here in CA. her name is Linda
search98@winfirst.com she should be able to direct you to the right searcher. Tell her Normajeanne sent you. Thanks for contacting me. Norma
