Elizabeth Woolverton (Pettit) - 108 Yeas Old at Death

Elizabeth’s date of death is very specific, but without sources. Date of birth is reasonable compared to Dennis. However, these dates are necessarily in error because they result in a 108 age at death.

Residue from some reference to a citation appears to be incorporated with her DOD. Is this copy/past regurgitation of another source? A citation would be helpful in resolving this.
