I am in the process of building a family tree. My children and grandcchildrens father was adopted and they would like to find their ancestoral background. He was born in Milwaukee, Wisc. Sept. 23, 1928. Was raised in an orphanage until the age of 5 or 6 years at which time he was adopted. The orphanage was just outside of Milwaukee.(Name of orphanage unknown. Any help would be appreciated.
