Hi!
FreeBMD shows that the death of a William Henry Brice was registered in the district
of Bedminster in the Qtr to Sept 1889. His age was given as 32, so he would have been
born in about 1857.
FreeBMD also has entries for the births of Ann Adelaide Brice in the Qtr to June 1883
and Ellen Maud Brice in the Qtr to June 1888 - both in the district of Bedminster.
I think it is likely that the Eliza that Pauline found on the 1891 census is the person you
are looking for and that the entry has been either incorrectly recorded or mistranscribed.
In the 1881 census, there is an Eliza Bookless born in Bristol in about 1856, working as
a general servant in the household of Edward Elphick, a tailor and outfitter at 15 High
Street, Bristol.
Also, do you know what William Brice's occupation was at the time of his marriage?
It's just that the 1881 census has a William Brice who was born in Wellington, Somerset
in about 1858. He is a lodger in the house of Thomas Newport, a cooper, at 17 Weir's
Buildings, Bedminster. His occupation is given as a butler.
There are a few other possibilities, but this seems a likely candidate for your William as
he may have settled in Bedminster after his marriage as this was where he worked.
Hope this helps!
