Our COLMER line goes:
George Henry COLMER 1909-1996 & Rose NEWTON
Arthur (Decorator) 1871-1940 & Eliza Ann Tarlton WATERS
Frederick (Carpenter) 1835-1905 & Eliza WATERS
(Frederick had three sisters: Selina, Hannah and Louisa)
John Churchill (Bell Hanger) 1792-1870 & Eliza. BUCKLER
William 1769-1826 & Edith CHURCHILL
If you come through the line with Slade as a second christian name (and where some changed their surname to SLADE) then your line descends from John Churchill COLMER's sister Hannah COLMER who had an ilegit son John Slade COLMER (1792-1853) he had a son Robert Slade COLMER who married a Jane ALLEN who were sentenced to death for murder, subsequently commuted to life in prison for John, I think she was eventually released. It's a very long time ago since I read all the court reports and things. John died in prison here in Kent, Gravesend I think. I am in contact with his greatgranddaughter , who would be the person to fill you in on all the details. Robert Slade had six brothers and sisters, one of whom was Mary Ann Slade COLMER who was christened in 1822 and married a William OSBORNE. Is this your ancestor? If it is, then forget John Churchill the bell hanger as he isn't in your direct line. . I would really need to know details of the line you have traced back so far, so that I can determine where you fit into the tree.
