This profile has frequently been confused with that of Olive Barnum (1769-1834), whose parentage is not known, and their birth and death dates and husbands have sometimes been interchanged or duplicated.
The US Census of 1790 shows an Olive Barnum, with one other free white female, living in Danbury, Fairfield County, Connecticut. However, that entry could refer to any one of three contemporaries of the same name.
A more-precise death date has not been found for her and the estimate given here is derived from the birth date of her last child. The date of 17 March, 1834, sometimes assigned to her, has been proven by valid, verifiable source citations to belong to Olive Barnum (1769-1834), wife of Asa Hoyt.
