The Social Security Death Index at Rootsweb gives the following information:
Birth: Sep 10, 1893
Death: Jan 1972
Last Residence: 65802 Springfield, Greene County, Missouri
Could this be the Della Herring to which I'm related?
Searching the Greene County, Missouri website probate records, I found the following:
Della M. Herring
Cross File: C10-994
Reel Number: *B62-0598
The date would seem to match the date of death in the SSN information. I have requested a copy of the probate records. I will be requesting a copy of the SSN application form.
The Greene County, Missouri connection is further confirmed by the information in this earlier post.
