So what if Queen Mary's false pregnancy was real and a daughter is born. So sometime in '55 a daughter is born who is named Catherine after the Queen's mother. However soon enough little Catherine is crowned and through the suspicions of the Spanish, a Protestant faction is successfully able to control the regency with the infant queen becoming one herself. Skipping forward a few generations assuming things generally play out the same way leading to a atl Spanish War of Succession but with a Protestant claimant in England.
How would things change?
Could this Protestant "Hapsburg" coalition end up being victorious?
Feel free to make a tree if you want, they make the discussion in my view.
