Note 246 — Chapter II · HENRY AND ROME. 1164–1172.
Reading edition
See the Gradus cognationis inter regem et reginam (Robertson, Becket, vol. vi. p. 266). “Hanc computationem præsentaverunt Pictavenses cardinalibus quando S. Thomas exsulabat, sed non sunt auditi.” The “computation” as there stated is wrong; but the right one really does leave Henry and Eleanor within the forbidden degrees. (See above, vol. i. p. 393, note 2{1161}, and p. 445, note 11{1418}). They were cousins in the fifth degree, their common ancestress being Herleva of Falaise.
