Probably no help, but adding it anyway:
Border Crossing, 15 April 1920
Annie Smith, age 40, born Kesh(?), Ireland, husband Chas D Smith. Lives in Toronto.
Visiting Frd(?) Fred Mallair (Grant Avenue address)
I don't have access to border crossings from the U.S. to Canada. I wonder if any clues can be found with John Russell's return to Canada? Or, did Amelia/Annie visit Canada after her arrival in the states?
