Tante Sidonia is a Flemish comics character from the Belgian comics series Suske en Wiske. In the franchise she is the aunt of Wiske and the adoptive aunt of Suske, of whom she both takes care. In the original Flemish publications her name was Sidonie, while the translations in the Netherlands named her Sidonia. After the series changed to Algemeen Beschaafd Nederlands in 1964 the character was changed to her definitive name Sidonia. She even announces this to the readers at the start of the album "De Nerveuze Nerviërs" ("The Nervous Nervii") (1964). In English translations of the series, she has been called Aunt Agatha, Aunt Sidonia, and Aunt Sybil. Source: Wikipedia (en)
