I have a large data base of DATE families from the Quantoxhead area of Somerset. I do not have details of the family group you are researching although I see your ggg grandparents Geoege & Jane living in Kensington, London in 1881 census. Also Mary DATE a widow born 1805 at Nether Stowey, SOM was living at Dodington, SOM in 1881. The GRO Index shows George DATE birth registered 1842 March Qtr at the Williton Registration Dist. and his children as follows: Henry Thomas 1875 Sept. Qtr.; Emily Jane 1876 Dec Qtr.; Francis Richard 1878 Sept Qtr. & George 1880 June Qtr all in the Kensington Registration District.
