Good day, 

I have been digging for Jewish heritage in Germany.  One branch of the family tree abruptly ended with the Paasch family, Johann and Johanna Paasch on another family tree. There may yet be other names but I'm starting here. He was born around 1781 in kraatz, Altmarkkreis Salzwedel, Sachsen-Anhalt, Germany. 

Can anyone point me towards Jewish communities in this region? Similar family names? Any burial records? Thank you!
