I'm Trying to find my half sibling everyone said its mostly impossible to find them what I want to know them my Birth Father is Robert Osburne. I have found three of my sibling, but I don't to have anything to do with the birth father can anyone give me advise I know this is a long shot but at least I'm trying..!

Without their names and with their father's common last name it is almost impossible.

How was the family separated? Sometimes there are Court records.
