Oh I see. I was planning to go to Kew sometime in the near future anyway, so here's another reason to go. I'll order a copy of that marriage certificate for Edward with a reference check on the name of Edward's father that I have already and go from there. Thank you all for all of the sources that you have provided me with, it is very much appreciated and I now have several routes to follow once I have confirmed that this is the man I think it is.
Thanks again,
Matthew
