Hi Stella - yes she was 11 years old and you can see her family in the 1911 census. Her parents were Emmett and Agnes. Agnes died in 1911 and Emmett stayed for a couple of years then left the kids and returned to the states. My dad was George. All the kids were separated so we have no record of Mabel after this one.
I don't believe the Grant Hartwick family is the "Ulysses" one.
