The Genealogical Record of the Barnum Family gives Catherine Hopkins as the name of Albert Barnum's wife but no documentary evidence has been found to support that statement. Several different sources give his wife's name as Maryetta, Mary Etta, Mariette and Maryette.
Mary Etta was the fifth of nine children. Source: Affidavits in application of Olive Day for a pension following the death of her son Edwin Day.
