I'm researching my Schiff family from Slutsk and have come across the name Sashe Kazofsky, Sophie Rosafsky and Hade Asofsky. Zalman Schiff born circa 1852 has a death record listing Hade Asofsky as his mother. Two of Zalman's children show marriage records with either Sashe Kazofsky or Sophie Rosafsky as their mother. I only have transcriptions of these records and when the family history centers reopen I hope to be able to view at least two of the images which hopefully might shed some light. Do you have any knowlege of any of these people?  I'm really at a roadblock with my Schiff family trying to trace back further than Zalman.
