I have a brother & sister looking for Regina as she was given up by her mother in the Philadelphia area in the 1950s. They have been searching for her and asked me to assist. The biological mother name is Marie Teresa Hartnett Mathis. She was married to a Albert E. Mathis, Jr. but believe Regina has a different father. There are 4 siblings (PA & OH)from the Hartnett/Mathis marriage.
