I would think that must have been quite an expensive wedding for those days. I like the cap the young gentleman on the front row is wearing or should that be the person the hat is wearing.
My great uncle Ernest Pay (aged 13) is the boy under the hat.

So far, in my efforts to identify people (and I have very few pictures of my grandmother's Wade family), I have found 28 potential attendees at the wedding for her 'side'
ie the bride's parents, her siblings and their spouses, and nephews/neices.
I have yet to count up the groom's 'side'. His siblings were all younger than him, but he had a large number of uncles and aunts and cousins.
I may start by counting all the people I can see to judge whether all, or what proportion, of these potential invitees actually attended.
Goodness me
