I so Birth Father or siblings!

My name is Crystal I was born Crystal Lynn McCombs I found my birth mother and all of my siblings. I have searched for three different men that I thought were my father. I've been told my father's name is John C Roberts. I do know he at one time had family in Florida as well as New York so he could possibly be in either place I have come to believe that he is between 60 and 70 years old. He had dark hair and dark eyes and tall very handsome I have been told. My birth mother has since passed and I have been told this from an Aunt Mary. He is the last piece of my puzzle I just turned 44 yesterday I would love to find my father it would make my life complete!
