I am looking for information on Paul, born late 1880s. He was married to Mary Riordan. They lived at 4301 26th St, San Francisco, CA from 1960 - 1964. She is the sister to my grandmother, Margaret Riordan Heehan. They also had a sister, Delia Riordan Downs, married to John Downs, who lived at 37 Nueva, Redwood City, CA about the same time.
