ISO birth father John C Roberts

My name is Crystal. I was born Crystal Lynn I was born in Washington Pennsylvania and was relinquished in Miami Florida. I was born November of 72. I have found my mother and my siblings and have researched three men I thought were my father. I just recently found out that a man named John Roberts was my father. He had dark hair and dark eyes was tall he would be between 60 and 70 years old. I have been told by a family member that I am the spitting image of him. Yesterday was my birthday and finding my dad is the last piece of my puzzle. I hope and pray he's out there somewhere! I was told that his parents lived somewhere in South Florida and he also had family in New York!
