Don,
I am the great granddaughter of Janie Thompson whom I believe is related to your grandfather. My mother always told me that on her grandmother's side we had a relative who died on the Lusitania. I am trying to put the pieces together now. Janie married Ninian Shirlaw from Lasswade Scotland and at some point went to Canada where in Winnipeg, Manitoba they had 3 children, one being my grandmother, Irene. Please reply and I can help you fill in some of the pieces! Best, Sara
