If your name is Seplowitz, Cheplowitz, Zeplowitz, Czepliewicz, Seplo, Seplow, Cheplo, etc., you may find some very interesting information about your family background here.
My name is Yerachmiel Seplowitz. I am a rabbi and Mohel in Monsey, New York. My grandfather, Rachmiel Seplowitz (Tzeplyevich?) came to America from Postov (Pastavi, Belarus) in 1904. His father was Pinchas (“Pinya der Groisser — Pinya the Big”) son of Yossel (Yosef) son of Pinchas, who was born in Postav around 1800.
I have been doing research on my family tree, finding a few relatives (including a fourth cousin, once removed, whose son’s Bris I later had the honor of performing) and a lot of MAYBE relatives. I have found that almost every Seplowitz, Cheplowitz, etc. that I have come across has roots in or around Postav.
