Hello,
I am the daughter of one of Blazej's children, Julia Rzewuski. Recently started on tree. Wanted to let you know that yes, Mary Kogut was Blazej's wife. However she died way before 1970. Matter of fact I believe she died when Julia was around 5 years old..so that would put her death around mid 1920's. Blazej DID remarry...however I don't know her name. Still searching. :) Don't know anything about their life/relatives in Poland
