I have seen a property that it could be on google earth, in Garston, but i would like to see it for myself, i will take pics.
The family does seem to have dispersed around about the same time.
The only info i know about Alfred is that he was a Butcher early on.
I found this

on the list it shows him as a fireman, if it is him of course, The birth dates are different so they could both be wrong, i am more confident with the first one.
