If you dont mind I would like to use this therad only for this purpose - as my work will continue I will present here the results of my research on family trees in 1395. And I will edit continually this post as the work progress.
There is only couple of issues I would be glad if someone from SV mod could clear for me.
1. In what form should I present the names - in their native (meaning the faction they represent, they are part of) or in english? I started with royals of Hungary and for help I looked in to the current state of mod and saw that there is used for hungarian in some era the name King Lászlo the Honorable (So I guess that according to that (á) it is in hungarian? Am I right? So for HRE I should use german form of names etc.?
2. Are you aiming at representing those royal family trees exactly like they were in 1395? Because right in my first faction I encountered problem - that wife of the Hungarian king died in 1395 (So I dont know if it is modable if it is possible for you (the modders) to "kill her" so she will apper ingame when you click on family tree as a dead in that grey. And also if it is a gameplay-wise because (thanks to gameplay mechanic - its not possible for FM to remarry) this way the king will never had any child or another wife. Nevermind this is up to you to decide - I will only try to show you the results of my research.
Kingdom of HUNGARY - Magyar Királyság
Royal family tree
King Zsigmond (27 yo) - Queen Mária (24 yo)(died in 1395)
King of Hungary
Zsigmond (hungarian),Sigismund (german) Zikmund Lucemburský (czech)(ruled Hungary 1378 – 1437) (born 1368) In RE he should be 27 years old. Later he became king of Bohemia (in 1419) and even later he was elected as a emperor of the HRE (in 1433)
There is a problem with his wife (Queen of Hungary Mária (Mary in english) she should be represented dead in this mod, because she died exactly on the starting date in 1395 - she was 24 years old at this time, and she was pregnant when she died.
Mária and Zsigmond had no child (the one she carried in her belly died with her). Zsigmond remarried in 1406, his new wife Cillei Borbála (Barbara of Celje) was cousin of his first wife mary and they had only one child a girl Elisabeth which was born way after RE starting date in 1409.
Zsigmond of Luxemburg was obviously from house of Luxemburg so maybe he should have the trait (Of Germani Blood) but in those times bloodlines of those nobles were so mixed that his ancestors were germans, czechs, polish, lithuanians....etc. And also in 1396 (a year after starting date) he was in command of huge combined army of various christian nations which he led against the Turks (who tried to gain some teritories at the expanse of hungarians)- so the traits could reflect this somehow (He must have been man of some reputation when he was allowed to lead such an army.)
Hungarian generals - there is a possibility to add Herman II of Celje (born 1365, in game he would be 30 years old) (Hermann Graf von Cilli - in german) as one of hungarian general. He was father of Zsigmund's second wife Barbara. And what is important: he served under Zsigmund in his 1396 campaign against the Turks and also saved Zsigmunds live in battle, for which he was rewarded with the county of Seger. But he was not of hungarian descent his ancestors were bosnian or serbian.
