Death9 Mar 1925, Mitchell, Davison Co, SD Age: 53
Burial12 Mar 1925, Bridgewater, SDF

Good afternoon,
I am trying to trace the family of Hannah Driscoll of Cardill. She married Thomas Purnell and had three children, Harry, Jessica and Oswald all born between 1904 and 1909.
I wonder if anyone can help me?
