Hi,
The problem the nearer you get to living descendants of Arthur is !! you can't write about living people on ancestry forum boards, but also as you are tracing forward you are dealing with actual people's present day lives into the unknown ? what these descents lives are like or who they are, what are there lives like or status, class, or what you will be walking into or dealing with. etc.
My cousins daughter (Clever academic girl with a uni- degree) did a bit of modern day near family short history on my paternal family side (Also normal ancestry back) through known near history also electoral registers and she wrote to a lot of them to have a family reunion at a local pub also my brother and I went.
In this case it was more academics with one school headmaster, a few teachers, a magistrate but a few load mouthed odd balls from - well lets a common low educated undesirable rough council estate ( who probably are/were great people in there own environment) who came thinking there would be free booze.
Thus probably better leave any descendants (who may have a photo of Arthur) to contact you by putting a notice in a local rag
