My ggg-gf Lewin LICHTENSZTEJN was born in 1832 in Mlawa, Poland.  He moved to Plock when he married Rayca LEDERBERG.  His parents were Nusen, who died in 1835, and Feyga, a sister of the Kuzmir Rebbe, Yechezkel TAUB.  
Attached is the 1822 death record for another Lewin LICHTENSZTAJN, who was a rabbi in the town of Kowal.  Could he be Nusen's father, my seventh-generation ancestor?  Can somebody translate the Polish for me?
