Alida Hearth-Woman was a prehistoric witch and an ancestor of the Harman family. She was the daughter of Senaida Hearth-Woman and the Ward of the Gate and a direct descendent of Hellewise Hearth-Woman. Alida presumably lead the prehistoric witch tribe and was mated to a man named Stormbringer. It is unknown if they had any children, though it can assumed they did, as the Hearth-Woman line was continued and still exists in the present.
The name Alida is Dutch, meaning "little" or "small winged girl" or "little/small winged one". It is also possibly a variant of Adelaide, the French form of the Germanic name Adalheidis, meaning "noble". Alida is one of the few Hearth-Women to not have a name relating to a particular deity.
- Alida is the last of the prehistoric Hearth-Women mentioned on the family tree.
