Joanna Caldonna Mariah Evergreen Willmon was her fulll name. This was confirmed by her daughter in-law (my grandmother Vester Lorene Guthrie) and was saved in a family bible. She was more commonly referred to as "Joe" by her closest friends and family.
Joe was born in 1869, even though her headstone states "1879" as year of birth. She appears in her first census in 1870 as a baby. Most of Joe's other records agree with this same date as well.
The daughter of John B. and Martha Jane (Pendergrass) Willmon, Joe was a resident of Alabama her entire life.
