Hi, you may already have the answer to your query re Donald Caskie, the furrier as I have just found this site!! He moved to Regina, Saskatchewan. I had the pleasure of meeting him when he came to visit his cousin,my grandmother (Isabella Murdoch Caskie -born 19.3.1884- father Donald Caskie from Islay). My grandmother's parents were all set to emigrate to Canada with other Caskies when her brother and sister-in-law died leaving 4 children!!!!
Cheers,
