Does anyone have any info. on my great grandparents:William Campbell and his wife, Mary. They are from the Virginia area originally,and later moved to Pittsburgh, Pennsylvania? William looked like a white man and was very tall and became the first black Policeman in a town called Homestead, PA about 1860 -1900. His wife, Mary was half Blackfoot Indian. They had (4) children: Ethel, Dorothy, Ruth, and Lloyd. Ruth went to California and married Alvin Carpenter; Ethel, Dorothy & Lloyd remained in Pittsburgh. Mary Campbell passed about 1965-67. She was my great granmother. thanks in advance for your time and info.
