I have a Donald and an Ernest Bozarth - but they don't meet all of the information you sent.To actually say they are your lineage I need some dates.The more accurate, the better, but close will help.About when was your father born?
Have you spent some real quality time talking to your Uncle Ira or your Aunt Ethel?If not, this is a great time of the year to take on such a project. What was Bernice's maiden name?
Have you contacted the foster care folks?
I will continue to look.Let me know anything more you can find.
