I am searching for any information on Richardsons in Allegheny County PA. My grandmother was Zelma Richardson, born 1902. Zelma married Ralph V. Anderson. She died in childbirth in 1933. She had a brother James who married Josephine Blair. A brother David, who died in a bicycle accident as a youth, and a brother Nicholas King Richardson, who served in WWI as a pilot. He was married to a woman in PA (Anna? Alice?) but left her and his children, and went west, and supposedly married an Indian. I know nothing from him after this. Zelma's father was Joseph Richardson, and was a grocer in Harwick PA in the early 30's. Her Mother was Alice King. They both died in 1933, within 2 months of each other. Alice died first, Joseph died of a broken heart.
