This is my mother-in-laws account. I am looking for my half sister. I believe Laura Trudeau is the right spelling. I last knew her to be about 32 years old right now and residing in Missouri someplace. I have no idea if she is married or anything else. We have the same biological father but something happened in which they lost contact. I havent been able to get any contact information. If anyone has any information about this woman, please let me know. I am also working on our father's genealogy.
