While working on my timeline "A Happier Wedding, A Greater France", I realised I had butterflied a bunch of OTL princes & princesses thanks to an Alternate marriage for Philip William of Pfalz-Neuburg. As I want to keep my timeline as accurate and plausible as possible, I decided to keep a genealogical record of the European Royal Families prior to my POD and of the ATL princes & princesses I'm creating.
I'm experiencing difficulties with the Wittelsbach. I got the basic concept that there were two branches in the origins: the eldest got the Palatinate while the youngest got Bavaria. The Bavarian branch isn't really my problem: though it was divided at some point, it was eventually reunited under a single bloodline that I can easily keep track off.
The problem lies with the Palatinate branch... Unlike the Bavarian one, it was separated in several branches and I have trouble in having a clear shot on all these branches. The fact that I also have trouble in keeping track of the order of these branch by primogeniture also doesn't help...
I'm thus asking on the board this question: what are the various branches of the Wittelsbach? Which ones still had descendants in the seventeenth century (my POD is in 1619)? And how do they rank by primogeniture?
