Well, it's nice to be proved right, even after two years, so long as you try not to be smug about it.
Reginald C Evens and Emily Skelsey (see my first post on the thread) married at (or registered at) the British Consulate in Etaples, Northern France, according to Service records on FindMyPast (now available in Lancs libraries). Both surnames are very rare.
Date range is given only as 1914-25, but based on the info given in earlier posts, the banns dates in Cubbington and the fact that their first known child was born in 1921, I'm putting 1919.
I say first known child - they might have had an earlier one in France. Any way of finding out? Also, would that marriage be in the actual Consulate, or somewhere else and merely registered there? Bit of a shortage of Protestant churches in rural France. Emily's family were Anglican, and anti-Catholic prejudice was stronger then.
(We stayed in Etaples briefly back in 1999. I don't think it has a Consulate nowadays.)
