Looking for info on my grAunt, Margaret C. Shanahan Crowley. Born in Buffalo, NY Dec. 8, 1900. Resided in Erie county for her entire life. Married John Crowley and had a son John Crowley. Wondering if she had any other children? If they are still living? She died on Jan. 6, 1972. Margaret had 2 brothers Joseph P. Shanahan born in 1896 and my grandfather born in 1899. Were there other brothers and sisters? Her father was Daniel Shanahan and her mother Mary Sullivan.
