Kind(eren):
Or "John nepos Waleran".
Burke says he was called John Monoculus as he had lost an eye. CP also gives him this name.
Keats-Rohan calls his son Pagan "son of John nephew of Waleran, a Domesday tenant in Essex" - and this led me to find John, with a mention of his father Radulf in Domesday people p. 284...
K-R: "son of Richard fitz Ranulf the Moneyer of Caen and nephwew of Waleran fitz ranulf" and she lists his five children: Payn, Eustache, William and Alice, abbess of Barking, and Alice, wife of Roger de Valoignes. And she then led me to CP's Vescy article where many of them are listed in even greater detail.
=======================
E: John 'Monoculus' (one-eyed) The ancestry of this John was confused by early sources who suggested that he was brother of Serlo de Burghof Knaresborough Caste, probably because Knaresborough later came under the control of John's son Eustace. This view is reported in BE1883 (Clavering), supported by BE1883 (Vesci), but was specifically considered and rejected by TCP which dedicated a whole appendix to the origin of Eustace FitzJohn (Appendix B in Volume XII/2). Some web sites identify John's father as Nigel of Halton , Constable of Chester. That appears to be the result of a confusion with John's son Eustace's father-in-law by his second marriage to Agnes who was daughter of William FitzNigel (FitzNiel) of Halton.
