Hugh Grenier

Hugh Grenier (died 1168/1174) was the lord of Caesarea from 1149/1154 until his death. He was the younger son of Walter I Grenier and his wife, Julianne. His older brother, Eustace (II), was prevented by leprosy from inheriting the lordship and it passed to Hugh.

The date of Walter I's death and Hugh's accession is unknown. Walter was still alive and ruling in 1149, and Hugh is first attested as lord by a royal charter of 1154. It is possible that his elder brother Eustace briefly held the lordship before joining the Order of Saint Lazarus for lepers. Unlike his father, Hugh had a close relationship with the kings of Jerusalem. He was a patron of the Order of the Hospital.
