Thanks to the many people who gave me leads on this.
For those struggling with the same matter, take a look at this map
(it is found in several other places on the web as well):

http://www.chalem.com/genealogy/maps/migration.htm

- it indicates that Jews migrated to the north east out of "Hungary" and
"Austria" in the 1300's and 14-00's, so could easily have continued
later - say in the 1600's and 1700's, landing up in "poland"
