I read with interest your information offer on Richard Tuckwell. I'm also tracing my lineage and have much information sourced from Charlie Tuckwell (my uncle) who received the information from MrAlan Thomson of Sydney.
Maybe we could exchange information. I have information concerning the De Tocqueville family who went with William the conqueror when they invaded England in 1066.
My address is 353 Gold Creek Rd BrookfieldQld4069.
