Good to meet you.
According to my research, Frederick William Gliddon b abt 1825 Hackney had 10 children. Richard Rawson Gliddon b abt 1850 was one of these. Edwin John Gliddon b 1860 (who is my husbands g grandfather) was another.Frederick William Gliddon (2) b 1848 was another son, I have recently made contact with his g granddaughter via the internet.
If you've been looking for the Walthamstow Gliddons you've found them! (Except we live in Chelmsford now!)
