Her death certificate records Anna Florence Spence, age 82 years 6 months 19 days, born 5 Nov 1863 in Ky, died 24 May 1945 in Sharpsburg, Bath Co., Ky, widowed, father Joseph Jones, mother’s maiden name Eliza Staton, both born in Ky, cause of death arterioschlerosis, informant Lindsay Manley, Sharpsburg, Ky, burial in Sharpsburg Cemetery.

Many family trees on Ancestry.com link her in as the mother of William Spence’s children. I find that rather implausible, since all of the death certificates I can find for any of William’s children are unanimous in identifying their mother as Anna Eliza or Elizabeth Warren. I’m not even sure that Anna Florence Jones married William Spence; the death certificate does not mention who she is the widow of, so it could be someone else.
