This is the unidentified wedding photo stuck on the other side of the album page. It is an Edwardian wedding, with a wonderful array of feathered hats, but looking closer, the bride and groom don't look like Evelyn and John (see photos below).
The above photo is presumed to be Evelyn and John who are honeymooning at the Grenville Hotel in Bude, June 1912,
and from the photo below, we can be certain that it is Evelyn.
this photo which names Evelyn and two friends, Sybil and Gladys Lees (all in fancy dress) is in Műrren, Switzerland and dated February 1912.
So as to whose wedding photo it is, I don't know, could the groom's pith helmet be a clue? More photos from the same page to come . . .
