I am searching for my father who disappeared in May 1942. I have found his second family recently and they believe he died or was killed in a steel mill in Ohio in 1972. They were not sure where or when as he had also left them. We know he had worked in the steel mills in Youngstown in the 1950's an my sister was born in Youngstown in 1954. His name is Thomas Patrick Walker. He was born 3-13-1912 in Butler, Co. Pa. He is caucasian and of roman catholic faith. I do not have a SS number nor can I find him listed on SSDI. I tried without success to get a death certificate from Ohio. Any help or ideas much appreciated. Thanks Jack.
