Think you can forget George Samuel Drawbridge married to Eleanor...
I think you need to concentrate on the George Drawbridge born 1871 Maidstone, Kent who was with wife Helen b 1869 Felmersham living in Knightsbridge in 1901. These were the pair married in Pancras in Sept 1895 where she was named Georgina Ellen Mason. The marriage certificate ought to confirm her father as James Mason & his father as Samuel Drawbridge.
While her birth index has her as Ellen Georgina Mason in Bedford RD in Dec 1865 her baptism at Felmersham on 4 Feb 1866 has her as Georgina Eleanor Mason, daughter of James & Sarah. In 1871 the family was living in Lewisham Kent where she's listed as Georgina Hellina born Radwell. In 1881 the family has moved to Worth Sussex, but Ellen Mason b 1865 Radwell is domestic servant in Lambeth, London.
Like you I cannot find her on 1891 census, but future husband George Drawbridge is soldier age 20 living in Farnborough, North Camp. In 1901 he was a Soldier in Royal Horse Guards. His Army papers show he enlisted 16 Jan 1890, went to South Africa 29 Nov 1899 to 5 Oct 1900 and was discharged 7 Jul 1902. I cannot find them on 1911 census.
However London Electoral Register has George Drawbridge & Ellen Drawbridge living at 30 Richmond Gardens, Hammersmith (South) from 1920 though to 1933, although she is listed as Georgina in 1932 & 1933. In 1935 at that address only Georgina Drawbridge is listed which is explained by the Death Index of George Drawbridge in June 1934 age 63 (=1871) in Kensington RD ref 19/196. Death Index of wife Georgina E Drawbridge most likely is the one found by JJen in Bedford in Mar 1941 aged 73 (=1868). The Electoral Register has a George Drawbridge living at 11 Birchin Lane, Langbourn, London from 1908 - 1915 but cannot locate that on 1911 census.
Suggest you get marriage certs & the 2 death certs to confirm all this.
If you do please keep us updated
