I'm wondering something... Would Berty take the name Edward VII like OTL or would he rule as Albert I if his father lived longer?
From wikipedia
When Victoria's son, Prince Albert Edward, Prince of Wales, became king in 1901, he took the regnal name Edward VII, in defiance of the wish of his late mother that her descendants would rule as double-barreled
Albert-[Name]s indefinitely. The new king declared that he chose the name
Edward alone as an honoured name borne by six of his predecessors, and that he did not wish to diminish the status of his father, with whom alone among royalty the name
Albert should be associated.
My guess is that if Albert lived longer his wife would not have insisted about the Albert - [name] double barrell. I would say that Edward would have wanted to be seen as his own man, and call himself something other than his fathers name.
