There is a Grace Thatcher, who died in 1949 at Toledo State Hospital, and she is buried in the hospital cemetery. Could be the same. Visit
www.toledostatehospitalcemetery.org for more information, or call the hospital, now Northwest Ohio Psychiatric Hospital and ask for medical records. If you are related, and they have her medical records card, they can copy it for you. Not much info, but it is a link to her past.
