George Senior's profession is listed as "living on own means". The 1881 Census has George Senior's father as a Wool Merchant, and his uncles as Solicitor and Wool Merchant again. In 1891 the family would have been in Austria, presumably.
J C Jubb is James Critchley Jubb. Probably a relation but not a brother by the looks of things.
Just been to check out Batleys War Memorial in Town Centre.
It has 3 Jubbs listed: Charles Jubb,James C Jubb and Joseph G Jubb
