Rohese was the daughter of Sibyl Corbet, but it is not known if her father was Herbert FitzHerbert or Henry I of England. Cawley lists her under both, and does not suggest a leaning towards either possibility. However, the estimated birth year of her son (say, between 1140 and 1150) suggests she was born after her mother's marriage to Herbert FitzHerbert.
