Hello, Benita -
I haven't come across the name William Bailey Dalby, or a Georgina, or the surname Bement, so it could well be a different family.
I have found William Bailey Dalby's marriage on FreeBMD:
Marriages Dec 1892
Holman Georgina Kensington 1a 187
and a possible birth of William Bailey:
Births Dec 1869
Dalby William Bailey Cambridge 3b 490
and just possibly his father's marriage
Marriages Mar 1855
DALBY William Bailey Cambridge 3b 585
though of course you would need to check these with the census records as well. Origins in Cambridge would suggest that it isn't the same Dalby family, as I have traced no Cambridge connections among any of my Dalby relatives.
