From Clansman July 1977

Oswin Barnsley joined Clan Line in 1952 as Fourth Officer in Clan Cumming.

He was appointed Staff Commander Edinburgh Castle in August 1969 and also served as Staff Commander of Pendennis Castle and Windsor Castle.

Prior to be promoted Master he was Chief Officer in King William and King Richard.

I believe that Ossie Barnsley passed away in 2011.
