Yes, but Daniel Gale, whom I am researching, was not a Chelsea Pensioner. I already know this, and like you I have access to the National Archive catalogue, which is after all, freely available on the web. There is more information on Himbury here:http://www.himburyhistory.co.uk/sgtjohn.html, and if you do a web search against his name you will find a biography available as a downloadable pdf. That biography was written partly with sources from the Green Jackets Archive, which is what I'm trying to get access to. The National Archive does not have the muster rolls. These are, in fact, at the Green Jacket Archive.

No doubt you find this very funny and amusing. I'll restrict my queries in future to serious forums.
