From Gertrud Juen Telfs:
I read your message on ancesstry com just today searching for some other items.
You mentioned a town in Austria called SERFARN
This ist probably SERFAUS, which is nowadays a famous skiing area in the Tyrol.
Some hundred years ago it was a very tiny little village with poor people living there on the financial base of agriculture.- There might have been some families called JUEN, because the name Juen was originally JOHANN which is a christian first name.
Lots of Juen`s are living around the area Serfaus oberes Gericht Kappl Paznauntal Arlberggebiet.
The surnames of my mother and father were both Juen but we coulf not find out how they were related
