Knaresborough, N. Yorks, John Alderson
This is probably a very long shot, but unfortunately my links are severed, as I now live in Hampshire. What I do know is that my grandfather was born around 1920 (and is still alive), and that he married an Irish lady around 1942, who gave birth to my father Michael in 1946 (who moved to Hampshire). He has one sister Pauline, and a half-brother Brian, both, as far as I know still living in Yorkshire.
