Hi all
Here is an update of what I have been able to find out. Gwynfryn (Gwyn) Owen Griffiths joined the RN in 1939 aged 18. Stationed at Clyde, he met Patricia Louise McLaughlin in 1942 at a dance in Greenock Town. Post war, c1946 they married in Glasgow registry office and briefly lived in north Devon before moving back to Brithdir, Glamorgan in 1959. They celebrated 60 years anniversary in 2006 Gwyn and Pat both passed away in 2009.
Hope that helps
