Hello Emmeline
It's absolutely fascinating! What an interesting family you have. I just wish that even one of my ancestors was rich enough to leave a will

The memorial inscription index just had on it the words 'Charlotte Mason later Gill' so I thought it was probably one of those later additions to an earlier gravestone. No other information at all, so I feel a visit to Melksham churchyard coming on! I'm going to be ferretting round down there before too long anyway so I'll add it to the list!
I found a promising looking death for Charlotte on BathBMD in 1884, so checked burials in Melksham and hey presto -
Charlotte Gill - Bathford - Feb 2nd (1884) aged 86
Also found William and Charlotte in 1851 - Ref HO107/1505 Folio 551 Page 21
at no 1 Milner(?) Place, Hackney, London
William C Gill - Head - Mar - 58 - Gentleman Fund Holder - Cumberland
Charlott Gill - Wife - Mar - 50 - - Glostershire, Bristol
Henry N Gill - Son - U - 30 - Ale & Porter Merchant - Glostershire, Bristol
Mary E Gill - Daur - U - 20 - - Midx, Dalston
Mary Evans - Serv - U - 20 - - Midx, London
Charlotte is still in Hackney in 1861 as a widow with her daughter and a couple of visitors. In 1881 she's in Bathford.
Looks like Charlotte might have left a will, too ( the Inland Revenue indexes are difficult to read as to whether there's a will or just letters of administration). Anyway, the executor or whatever is John Gill and it's in the index as 1884, so might be worth getting hold of. If someone can check the microfiche indexes of wills and admons rather than the Inland Revenue list, it should give more data. The transcription of the index is -
Testator -Gill, Charlotte; Residence - Bathford, Somt; Executors - Jno Gill; No of Affidavit - 3752; Court - PR; Register - W (hopefully for Will); Folio - (blank)
Can't find a will for William though (died 1854)
Hope that's enough to be going on with for now!
Regards
Angela
