I came across a random reference posted by "I don't know" and the website "I can't remember" at the National Archives in Kew. I had typed in John Horspool and then clicked on a random entry that said that John Horspool(Bedford, Harlington) was the Grandson of a bastard who was the son of the Duke of Bedford. I had to walk away from the computer and when I came back the reference was gone and another patron was doing their thing. I cannot find that reference again and I have spent too many hours searching. Can anyone help.

thx
