Genealogy / Michael Slotwinsky & Yuska Opleta - Galicia, Ukraine [4]

I have begun researching my great grandparents who were born in Galicia, Ukraine. My great grandfather, Michael Slotwinsky was born about 1880 and have yet to find a birthdate for his wife, Yuska or Uska Olpeta. I do not have their parents names or any further information other than they had 9 children and immigrated to Manitoba, Canada in the early 1900's. My grandfather was born in Manitoba, Canada. I would like to learn as much as I can about Yuska and Michael as this side of the family is a mystery. My grandfather’s birth certificate does not show a date of birth for his parents, only Galicia, Ukraine. Any information or direction of where to search would be greatly appreciated.

Thank You.
