I am trying to find out information on the marriage of my grandparents, which I have just heard may have taken place in Douglas, Isle of Man. His name was William Sutherland and my grandmother's name was Lilian Ada Ferraby, originally from Barrow in Furness. Lilian Ada's sister, Florence Ferraby, married a captain on the Isle of Man Steam Packet, Ted Corkhill. I understand they were married in 1910 and I am trying to find out any details.

If anyone can help I would be grateful.
