Through a series of very bad circumstances (a mix of conversions to Catholicism and cases of infertility), upon the death of Prince William of Gloucester, the distantly related Sophia of Hanover and her descendants were rather surpringly the closest Protestants after Queen Anne in the British succession, skipping all the descendants of Sophia's Catholic older siblings. Many TL ideas just make William of Gloucester survive of have Prince Rupert have descendants on the throne. I have a more obscure potential POD for my TL idea that involves another older brother of Sophia, Edward of Palatine-Simmern. Prince Edward did actually have daughters irl but as he had converted to Catholicism, all of them were also Catholic and not likely to take the British throne. One of them, Bemedicta Henrietta, was married to the likewise Catholic convert, John Frederick of Brunswick-Lunenberg (actually uncle of George I). They had several daughters, all Catholic. However per my POD, Benedicta dies ~50 years earlier, in the 1670s (in childbirth or some other mishap) and as a result, when John dies in 1679, rather than the children being brought to France with the mother and brought up Catholic, they stay in Hanover with their father's family (I.e. the more prominent OTL Hanovers) and are raised presumably as Protestants. This puts their daughter Charlotte first in line after Anne (instead of her own cousin George) begging the question, who would Charlotte have married in the meantime (Modena like OTL seems out) and if like OTL she has a son who lives to 1780 what is a British ruler with a 66 year reign in the 1700s going to look like? So from one death does this chain of events seem plausible or interesting to people? Any comments, speculation, suggestions?
