Perhaps it is Clihline, or something along those lines.  There’s very few people with a surname similar to this so it gives me a fighting chance of finding the parents of the groom.

Is finding the parents of the groom the main focus of your search? and identifying Elsie's middle name just a possible clue?
Do you know definitely Elsie was sister of the groom?

I wonder if it should be Caroline 

I just thought that as she had seemed to have problems spelling Elsie maybe the same was true with her middle name 

[LizzieL]

Or Christine if she was badly dyslexic

If she was also the daughter of John William (soldier), perhaps it was a place name (abroad) or name of a battle where he was involved.
Just thought of that when I found a birth record for an Elsie Mafeking Gardiner.
