Daughters of James McKinlay & Christina Aird. Isabella Robertson McKinlay born in Hamilton Lanarkshire 1894, Mary Beveridge McKinlay born in Dalserf Lanarkshire 1899.
They both emigrated to Canada (I believe with assistance from the Salvation Army) in the 1920s.
I know Mary was living in Vancouver BC in 1929, probably not married as she was a witness at another sister's marriage (not Isabella) and gave her surname as McKinlay.
At least one of these ladies married, because I know she wrote to her sister in New Zealand, but I have no idea who either of them may have married.
This is a long shot....... but do I have any Canadian cousins out there?
