He [Roger de Scales] married Muriel.[f] The date of his death is unknown, but may be placed before 1198. [Complete Peerage XI:496-7, (transcribed by Dave Utzinger)]
[f] Dugdale, Mon., Vol. iV, p. 2o6. Blomefield (op. cit., Vol. IX, p. 20) suggests that Muriel may have been a daughter and coheir of Geoffrey de Lisewis, whose father William founded the priories of Normansburg in Rainham and Crabhouse in Wiggenhall, on the ground that Lisewis "appears to have held Rainham, with Gateley, Islington, Clenchwarton, etc. under Hugh de Montfort, the moieties of all which came about the same time to Ingoldesthorp and Scales" (Vol. vii, p. 124.). The holdings, however, of the two latter families in the places named were not identical with the Lisewis holdings. Like Scales, Lisewis held of the Honor of Hagenet or Haughley, by Castle guard of Dover (Red Book, pp. 614, 706), and a Geoffrey or Godfrey de Lisewis was so holding in 1211-12 and (if the list records the contemporary position) in 1261-62. The lands held in coparcenery by Scales and Ingoldesthorp were certainly derived from Beaufou.
