...I like the idea of Louise of Savoy: Secret Lutheran Sympathizer and it's a nice way to introduce the Reformation to England. But, uh, Luther wasn't even a monk in 1504. The 95 Theses weren't published until 1517/1518 IIRC.
If Henry Tudor (OTL Henry VIII) is destined for the Church TTL with two older brothers, perhaps in due course he introduces his intelligent and classically educated sisters-in-law to such aspects of English religious history as John Wycliffe and the Lollards. Catalina will, of course, be horrified but Marguerite could still be your point girl for the Reformation in England. This would work even better if Arthur dies before he and Catalina can have a son.
I completely get what both of you are saying, and I did know that Martin Luther was not active at the moment (I put it in an A/N at the top of the chapter) it was just that I was struggling to find a ‘Protestant’ writer at the time that I could use.
I think that the idea of Henry introducing her to the Reformation ideas is very interesting, but I wanted her to already have sympathies before moving to England in order to slowly begin to influence William and also to be the one to steer Henry further from the Catholic Church, so now I’m unsure as to whether I want her to already have sympathies or whether she should develop them in England 😂
I’ll have to have some time to think about it before I edit this chapter. Thanks for your replies!
