Great list. I'd really like to see a timeline about it some day.
Me too but it would be a mammoth task. I may chicken out and let someone else do it if they want to.
In reality, of course, the second half of the list is somewhat fictitious, as the persons named were born after the PoD, and so would probably either not have been born at all, or would not be identical to those who bore the same names OTL. On the other hand, since I've kept the US out of WW1 (and so
possibly butterflied WW2 away as well) there will be 100,000 plus men surviving to father kids who never existed in our world - perhaps including a President or two. Hence my inclusion of Champ Clark III, though I haven't checked if such a person actually exists in our world.
