"Information I had been given said that the IRVINE family owned a fishing fleet and lived in Aberdeen, opposite a golf course. This might be true of John Hennell IRVIN, son of the above Richard IRVIN, however, whether Barbara's father owned a fishing fleet, I don't know."
Not sure if you are still searching, or if this will help, or indeed if you have this already, however ...
My Granny was in service with Sir John Irvin (born North Shields 16/3/1874) in Aberdeen (86 Queen's Road) in 1922. He died in Aberdeen 25/3/1952 and is buried in Springbank Cemetery, Aberdeen, along with his wife Mary Boak, and daughter. From what I have gathered so far, he did have a fishing fleet in Aberdeen. The property is or has been redeveloped as "luxury apartments" but I'm not sure about the golf course.
