Rachela Czyzhevski, was married to my ancestor, Jan Mikhailovitch Robak(born 1746), both lived in the estate of Naraievshtchina, Mozyrskij Ujezd. 3 children: Josif(b.1776?, Leon(?) and Teresa(?).
The marriage would be contracted in the catholic church, she would seem to belong to the noble family but her first name is a puzzling one. Possibly jewish convertite, so called Frankist family?
