Muriel de St. Jean

   Another name for Muriel is Muriel de St. John.

  General Notes:

A manuscript recording the founding of Boxgrove Priory, Sussex names "Mabiliam" as the daughter of "Willielmum et Robertum se sancto Johanne…Murielem sororem suam" and her husband "Reginaldo de Aurea-valle", adding that she married "Adæ de Port"

~Dugdale Monasticon, Vol. IV, Boxgrave Priory, VI, p. 646.

• Background Information. ¹⁴¹
According to the Fundationis Historia of Boxgrove [Dugdale, Mon., vol. iv, p. 646], Mabel was daughter of Rainald d'Orval by Muriel, daughter of Roger and sister of William and Robert de St. John. Round accepted this provisionally on the ground that the Historia was obviously more trustworthy than such narratives usually are. That Mabel was the heiress of Orval is certain, since a gift of William d'Orval to the abbey of Blanchelande was subsequently confirmed by Adam de Port and Mabel his wife as the gift of their predecessor [Archives de La Manche - Série H. Inventaire sommaire, vol. i., p.201; H. 1270].

It is equally certain that Halnaker came to Port through Mabel and her mother, and this being so the mother must have been a daughter of Roger and a sister of William and Robert de St. John, not only on chronological grounds but also because, if she had been of an earlier generation, Roger's brother John de St. John and his male issue would have inherited to her exclusion. Since the wife of Robert de la Haie was named Muriel and they were the parents of Cecily, Roger de St. John's wife, it is quite likely that Roger's daughter should have been named after her, and on this point one seems justified in accepting the statement of the Historia.
