For Dlugosch there are 81 on Yasni with different names.
Among the most common last names on Yasni Dlugosch is on position 4446.
In my opinion it has to do with the Polish word for "long" Dlugy, where the L will be written with a line through it. Accordingly, means Mr. Dlugosch Lange to Mr. German.
