My Pearl M. Schultz was in Jackson, Michigan, from 1942 to 1957, as located in the Jackson City Directories at Ancestry.com. The Ancestry collection stops at that year. Would anyone know if any later city directories are available and where I could locate them? She was 70 years old in 1957, and I wonder if a later directory might give her date of death, which I have not been able to locate at all. At this point I am assuming that she died there. Thank you.
