Just out of curiosity I have Elizabeth Walsh as his 2nd. wife is this what you have?
Oh wow, I didn't even have that - I only realised the initial in the '51 census was perhaps an E instead of a G and got distracted elsewhere (trying to find more info about James Thomas Richards' dad, James Richards who might be a real toerag if he's the one in newspaper reports committing all sorts of weird and wonderful crimes.)
But you've got it spot on with Elizabeth Walsh, I've just had a look and the address given for the groom matches what I had. Thank you!! It feels really good to be able to give names to our ancestors (and second wives), it's like gathering them all in again after having lost them for so long.
