HOUSEHOLD CARR MARY JANE F 1910 6 MONTHS Gateshead Durham
This would have made her born in October of 1910.
Mary Jane was only about 7 months old, when her daddy (Stephen Carr) left for Canada in April 1911. Stephen did not know that this would be the last time he saw his little Mary Jane. I wonder how they said their good-byes. Did they hug each other. Did they wave at him from the dock crying as the ship left, or did he just leave as if nothing was different.
A few months later (September 1911), Sarah Jane (Catterall) Carr and the six children left for Canada. Little did they know that Mary Jane would not make the trip. She died at the age of about 11 months -- she didn't even see her 1st birthday. Mary Jane died somewhere along the way to Canada, which was past down to the other family meembers. At this time, I do not know what or how she died, but she would have died in September 1911.
