GMac78 - thank you so much!! That's marvellous!!!
Fantastic work - thanks to you and to all the restorers. There's my grandad and gran large as life and twice as natural

Xin, the mystery man, either my greatx2 grandfather James Pay, or possibly my great grandfather William Thomas Wade, is next to the bride, my grandmother Mabel Emily Wade. I have no idea who the lady sitting on the other side of him is.
In terms of positioning, the groom's father is standing right, in the light suit, and his wife the groom's mother is standing on the other side, next to the shed.
The bride's mother is, I think, just in front of the groom's mother, sitting in the row with the bride and groom.
So potentially her husband, the bride's father, could be the mystery man.
However, my greatx2 grandfather James Pay, was 71 at the time of the wedding, and would - I think - have wanted to be present at his eldest grandchild's wedding. And if the mystery man isn't him, then he isn't there.
I fear I will never know. I think mystery man looks like my brother, but neither he nor my s-i-l see any resemblance.
But it's a lovely picture none the less!!!
Added: by the way, do we all think that's the vicar standing just behind the bride and groom? Ian thought so, and It looks like it, but isn't that quite unusual in photos of this type? I don't believe I've seen it before?
