Pearl FINKELSTEIN missing death records 1891
I do not know the specific answer to your question, but I have many relatives in Winnipeg. The majority of them who have passed away are buried in Hebrew Sick Benefit Cemetery, 2605 McPhillips St., Winnipeg, Manitoba, Canada. Maybe the cemetery has some data on your family.
Researching: PEKER, PACKER, BECKER, PECKER from anywhere in the Ukraine, especially towns within a 100 mile radius for Kiev (Korostyshev, Zhitomer, Koristan, Brusilov, Khordorkev, Rudni).
