A person referred to in a historical record, or a collection of personas. We say persona when we know that it's a person, but we don't know which one. Consider the five contemporary Jesse Littrells in Lauderdale County, Alabama. If you found a record, you wouldn't know which Jesse it was. In OWT, each record is considered to reference a different persona that was one of those five peopleâ€”and then we try to stitch them together.
