Firstly, i hope that you are still using this e-mail address as i replying to your posting on the genealogy.com forum for Tonks back in 2002.
I am a descendent of Ellen Elizabeth Tonks b 1852 in Birmingham, her father was Frederick Tonks b 1828 and his John Tonks b 1798. I am currently waiting for both death and marriage certificates to arrive for Frederick b 1828 and wife Harriett b 1828 and would be happy to forward you copies if required.
I would be gratefull to receive some information or copies of material on these people if you have any?
Do you know what relation Thomas Tonks was to John?
