David, I can't answer your question about that site, especially since I had to have Google translate for me -- but the link leads to a fascinating story, and mentions Adrian Richerdsson Falkener, who I had just run into in my own research (that is, if this is the same person as Adrian Falk or Falch -- and I have the idea he may be because I think his wife's name was the same.
Anyway, I was really glad you posted this!
