To me the most interesting development would be if the two children turn out to be prim, proper and successful; unlike Charles and Andrew. I doubt if anything changes re succession but it would put more pressure on teh institution of the monarchy.
Not sure what you are suggesting? Hopefully not a marriage!
I don't think a child of Albert or Alice Windsor is going to be any more important or high profile than Viscount Linley or Sarah Chatto is now, which is very, very minor.
It is a recomendation based on readings into modifications to other titles that George V did earlier. The Monarch is the fount of all titles and George VI apparently created the title in 1937. That any children of Edward and Wallis would receive a title would be dependent upon their uncle, George VI.
Very true, but I still think it would have been needlessly punitive.
