If the woman lived in Florida for any length of time, perhaps a death notice or
obituary appeared in a newspaper there.
The SSDI lists the state in which the SS# was issued. Perhaps she died or was
buried in that state. That would be a starting point. If she was buried in
here "home" state then a burial permit would have been issued. That will tell
where she died.
