Hi Pat. I will be having a guest and her daughter visiting on the 16th. She grew up on Fehmarn Island, translates ancient documents, well from at least 1400. She is familiar with the area you are talking about. Some interesting burial practices, as I recall they would at times take their dead to be burried in Norway.
Given that she has translated many wills, stories, church and government documents etc. from those time periods, and done genealogy work she might be able to give you some information. Or perhaps some people you could contact.
If you tried to contact her at home, she would never respond. She charges for her services, and is too busy with translations and language courses. While visiting, she is not under that pressure, and has agreed to communicate with you from my home at no cost.
My email is
