There is little information on Corisande, as she is only mentioned on the family tree. The tree states that she was born in 1729, presumably in America. Through her mother, Corisande was the granddaughter of Maeve Harman and Hunter Redfern, and the niece of Garnet, Lily and Dove Redfern. She is also technically the half-niece of Chervil Redfern, Hunter's only son, thus making her a cousin of Tormentil Redfern and second cousin to Delos Redfern, though they were born and lived centuries apart. She was married to Declan Morrigan and had at least one daughter, Fianna Harman. It can be assumed that all modern Harmans are descended from Corisande.
The name Corisande may derive from Spanish, meaning "heart" or from Greek meaning "maiden". It first originated in medieval romances.
- As her grandfather Hunter was a Redfern, Corisande is biologically related to the family, as well as being considered cross-kin via the blood-tie her grandmother Maeve did with Hunter. Neither Corisande or her mother are considered Redferns themselves, as they were born witches, though their descendants are considered 'cross-kin' or 'cousins' to the Redferns.
