Thanks for the spot
@Clandango .
As to the references, I do try to look for data in the language of the country I am researching as I think they will have more information on the area/events I am looking for. So Guelders info came mainly from Dutch sources.
I dont speak any other languages but it is usually easy enough to read a map without, then I use the auto translate facility for the text and interpret what I get.
As far as I am aware Mark never appeared in the title, I suppose the fact they were the ruling house was enough of an ego boost!
The yellow circles were once part of the Palatinate [before 1504]- I left them on the map.
Thanks for Friesing, there are also parts of Brixen and Bamberg I have missed off. Also surprised that no one noticed that I left France as France-Milan in the key after Spain took it
