The witnesses to the marriage of William Thomas George and Sarah Pope were Frederick and Amelia Walton.
I've just received their marriage record:
13 March 1865, St. Matthews Church, St. Georges East, Frederick Walton, 22, bachelor, bricklayer, son of Frederick Walton, bricklayer, & Amelia George, 21, spinster, daughter of Thomas George, butcher.
I think I have this couple in 1871 as "Whalton" with no children. I can't find them after 1871.
I believe Amelia George was the sister of my William Thomas George. This ties in to the George family I have tracked backwards in the census.
Based on LDS IGI records, I also purchased these birth records, which tie in with the census:
7 June 1840, St. Leonards, Shoreditch, Amelia, daughter of Thomas George, weaver, and Elizabeth George formerly Robinson.
4 April 1848, Bishopsgate, William, son of Thomas George, butcher, and Elizabeth George formerly Robinson.
Amelia George & Frederick Walton Details.
i have checked Freebmd and Amelia George is def. listed as being born in June Qtr 1844 in Westminster 1 442
there were three Frederick Waltons born in 1843 which yours would have been according to the marriage certificate.
the one that jumps out at me is
Frederick Walton b.dec qtr 1843 Bethnal Green 2 53the other two are Frederick Walton b. sept qtr 1843 New Forest 8 82 (new forest is Hampshire) and Frederick Walter Walton b. dec qtr 1843 Wycombe (Buckinghamshire) 6 410, as there was no mention of a middle name on the marriage certificate you can be pretty sure the fist one i listed being born in Bethnal Green is yours.
there were twins born in St Georges East in March 1865 (the same as the marriage of Amelia and Frederick) which i think is more than coincidence however you cannot be sure without purchasing their birth certificates. Alice Walton St Geo East Mar Qtr 1865 1c436 and Daniel Walton St Geo East Mar Qtr 1865 1c441
i believe that Daniel may have died in Q3 1869 in lambeth although he is listed as being one year old, as far as i can see there were no Daniel Waltons born in 1868 and Daniel b.1865 is the closest age wise.
the baby info. is all circumstantial.
