I have been searching for my biological father for years. I have no idea of his identity. I did a DNA test and found a third cousin. I was born in Smithtown, NY in 1979, and I believe him to be in his 50's. I think he is of Greek, Italian, jewish, descent. I was able about to search the third cousin on Facebook, when I found she lives in Holbrook NY which is right next to Ronkonkoma where I was raised, so I think I am close! I messaged the person but have yet to get a response. I dont know what to do from here. Does anyone have any suggestions?
