I was about to start a new discussion (as i am planning to start MPing and RLing the Salm family soon-ish) when I spotted this old discussion.
Chasing up the tree we have, in order:
Heinrich von Salm, Graf von Salm Salm, Rhineland-Palatinate, Germany
Hermann II von Salm, Graf von Salm no place name
Count Hermann von Salm Luxembourg
Giselbert I, count of Luxembourg Chateau DE Salm, Luxembourg, Belgium
I think that without finding specific individual evidence it looks like the intention in creating these profiles is that all these people are thought to have been born in the ancestral home at Salm (modern day Vielsalm)
As I said a few years ago Salm is not and has never been in Germany, to expand on that Rhineland-Palatinate dates from 1946 so cannot be right. Luxembourg is in Luxembourg but Salm is not.
Does anyone have an issue with me changing these less than accurate location names to Vielsalm, which may or may not be correct but at least consistent and logical. Either that or we can just blank them all due to lack of evidence.
