My Joseph Catalfo, for whom you did some research, worked in the quarries from at least 1910 - 1927 or so. He had health problems from that time on. Family story says that he was received a blow to the head while working in the quarry and apparently was never able to work after that. They lived in South Amherst at the time he worked in the quarry then moved to Cleveland sometime before 1928. I don't know the name of the quarry. Sharon
