Tortus
From Zelda Wiki.org
Tortus is Anju's father and the son of Anju's Grandmother. By the time the events in Majora's Mask occur, Tortus is already deceased[1]. We only know his name because Anju's Grandmother often calls Anju and Link by the name "Tortus"[1]. Anju must constantly remind her grandmother that Tortus is no longer alive[1], but she never appears to fully understand[1]. However, there are a few hints in the game, such as the grandmother's journal, that suggest that she might be faking her senility, and may find mentioning Tortus the way she does a convincing way of maintaining this illusion.
