LePoidevin/Berry

[brittany]

I am trying to find out about my uncle Gerald Berry who married Jean Mabel LePoidevin in WestonZoyland Somerset in 1951.I have been told that Gerald lived in Guernsey after he married. Jeans father was Alfred John LePoidevin and his occupation was listed as a Gas works operative on their wedding certificate. Can anybody help as I am sure I must have cousins out there somewhere?
Thank you
Carolyn
