I'm not buying it. Other sources say she died
February 1, 1876 and was buried
February 4, 1876 and some volunteer paid for that marker to be placed at her grave in
September 1997.
If the person who wrote the inscription couldn't get the woman's age and year of death right, which are in the historical records, what are the chances of the remainder of it being accurate.
(It's like someone is using a dead slut for attention whoring.)
