K-R, DD 596 and 597: Probable father of Robert, Thurstan I.  K-R disagrees with the received opinion that Henry was the brother of the Turstin who held the Mowbray fees in 1166 and says Henry was the father of this Turstin and of his elder brother Robert, who held the fees until his death 1141.

K-R allows that Henry may have had an earlier Tursin as a brother and that this Turstin (and he) were somehow connected with Henry earl of Warwick bef. 1000.

CP: Poss. s. of Roger de Beaumont & thus cousin to Henry, earl of Warwick.

TFPL, Aug 2006: In Collectanea Topographica et Genealogica, Vol I, (pub 1834) p.145, there is this very interesting pedigree from the Plea-Rolls (etc):

[Poss.] Fo. 14b.  Esson’ et pl’ita coram Rege J..

Nescil’ annus

York.  Turstanus de Monte fori peti med ville de Langeton v’ Eustachiie de Vescy.

  Galfr’us Murdrak
  |
  Juliana fil’ sua
_|__________
|                      |
Rob’tus        Henricus
                     |
              Turstan nunc potens

This seems to confirm Keats-Rohan’s account - see above - and gives two generations prior to this Henry.
