John Francis Clare

I am trying to make contact with my brother, John Francis Clare who was born in 1952 and lived on Annadale Drive Marino before he went to the States. He lived in the United States for a while but returned back to Ireland in 1990. His son Fergus is also looking for him. He has a brother, Harry, living in the United States. I have tried everything, came over to Ireland to search for him and to no avail. If you know of his whereabouts can you contact the webmaster.
