Walter d'Ayncourt or Eyncourt, 1st lord (a 1066)
According to BE1883, Walter (cousin to Remigius, Bishop of Lincoln) may have been a kinsman of the Conqueror, probably through his mother. BE1883 identifies him as the 1st baron, and calls his successors barons also, but notes that they were "barons by tenure, until summoned to parliament by writ, 22nd EDWARD I". We use the diminutive "lord" rather than "Lord" until the Edmund who was so called to parliament, thereby being consistent with TCP and BE1883, albeit with the latter only until that Edmund whom BE1883 identifies as the 8th baron. From the father of that Edmund we change the spelling of the family name but note that this is not followed consistently by all sources.

  iii. Roger d'Eyncourt
  Thoroton follows the senior line above down to John father of Edmund father of Isabella. Thoroton also shows a Roger in this generation, connected by dotted line that presumably implied some uncertainty, who is shown as probably father of Robert father of Roger father of Roger father (by Joana, dau of William Thorp) of John of Kanpthorp & Parkhall who is identified as father of the William who we show above as the 2nd Lord. We give precedence (above) to the pedigree supported by TCP (and BE1883).
