Date of death is uncertain, however, there is a death certificate for a Mary Trzeciak who died at around the age of 85 on 18 Mar 1951. She was living in an old age home (St. Joseph's Home for the Aged) and apparently the person (Josepha Kwiatkowski) who was the informant on the death certificate knew nothing about her other than that she was a widow. Burial was in Calvary Cemetery.
