Red box as I was about to post - this is how I read the 1891 entry, which is VERY smudgy!
1891
RG12/2228/71/13 - 40 Gt Brickkiln St, Wolverhampton
Ann Maria [INK BLOT] - Head - M - 37 - Warehousewoman
John Will (?)TATE - Son - 13 - Warehouse Boy
George (?)TATE - Son - 10
Richard WATKIS - Son - 7
William WATKIS - Son - 4
(All born Wolverhampton.)
I suppose the older boys' surname might be GATES (which fits the marriage Carole found), although on the image it looks more like TATE/LATE/SATE.
(Going out now, but I'll catch up with this thread later - I have an indirect connection to Watkiss in Wolverhampton, but I'm not sure whether it's the same family!)
