Hallo Samantha,
sorry this is the wrong forum. Anyway, because the Pfalz-list obviously only
communicates in German I�ll try to give an answer.
FEYEN is a suburb in the south of TRIER
PIRMASENS is a small city about 60 miles south west of TRIER
You could try to write to the following adresses.
Both should be able to give you information if they have the birth- and
death-registers or where to find them.
Hope they are willing to help
