Hi Fred,
Gertrude Snelling was the sister of my great, great grandfather David James Snelling, listed on the census as James Snelling. I had noticed on the census that Gertrude was listed as Snelling in 1891, then in 1901 as Brown, so I looked up her wedding and found the Charles Brown connection. I didn't know about the Sutton marriage though.
Gertrudes brother David Snelling, i'm not sure if he was known as James, he was born David James Snelling, but everywhere I have found he is listed as James. There was another brother I know of, Peter, but I have no information on him yet.
David lived in Grantham Road which is right next to Little Ilford Lane. He had 5 children who all continued to live in the same area, but eventually moved away during and after the war.
So looks like there is a connection. If there is anything else you would like to know, Please get in touch. I do have some more information on Gertrudes parents if you are missing this. Anything else you know I would be interested to hear from you.
Thanks, Regards
