My grandfather was Frank Oswald Jagger. He was born in the late 1880s or early 1890s on Prince Edward Island. As a child the family moved to Mass. As was too common at the time he received a 4th grade eduacation and then was put to work in the mills. At some point the family moved to Colo. He was married, lived in Wyoming, Canada, and finally back to Pueblo CO where he died in 1949. He had a number of brothers and sisters and there are still Jagger's in the Denver, Colo Springs, and Pueblo area.
PS. I'm just getting going in this genealogy thing so I don't have a lot of information.
