In my family database, I have a
Georg Gehann, born Jul 31, 1885 in Grosslasseln,
married (Dec 18, 1910 in Grosslasseln)
Susanna Sara Schell, born Feb 19, 1892 in Grosslasseln.
Emigrated to USA, 5 children, no further information.
Is there a connection?
Seiler, Zimmerman, Gehann, Schell, Muller are all Grosslasseln surnames.
Per your original question, few Saxons are still living in Romania - most emigrated to Germany in the 1990's.
