Well, I suppose it means that this Edward WILD married Isabella HALE, although I can't see an Edward-Isabella couple on census at the moment...

It looked a good match, but if the record office say the cert isn't for Edward and Mary, it can't be the right one, I'm afraid.
ADDED: There's a death in Shoreditch in 1855 for an Isabella Jane WILD, so guess that's her.
