I haven't checked any obits but I believe Mary d 14 Dec 1963 in Toledo. I don't think she was born in Michigan but possibly in Poland, Germany or Russia. This Mary was 82 and a widow. Her husband, Stanislaw/Stanley d 17 Feb 1958, also in Toledo.
They had at least 8 children that lived to adulthood and I am reasonably sure that one is still living.
