I saw that but surely it must be a different Mary Gilmour because in the marriage to Robert Cunningham in 1849 it said she was a spinster?

I have a rumour that there is a possibility the Spruston's came from Ireland. If they came by boat are there passenger/immigration lists for people arriving from Ireland. That's one of the ways I have traced the Sprustons from Whitehaven to Canada later on.
