Agatha de Aguillon, heiress of Cockfield

Origins

From https://en.m.wikipedia.org/wiki/Aguillon_family

Sir Robert III (died before 1249) around 1217 founded Flitcham Priory.[22] and before 1239 he and his wife confirmed a grant by her father to Sibton Abbey.[23] Before 1239 he was married to Margaret, daughter and heiress of William Fresnay, and then to Agatha, daughter and coheiress of Fulk Beaufoy, lord of Hockwold in Norfolk.[24] After his death his lands were divided among his four daughters:

• Ela or Isabel (died before November 1251), who before 1231 married Sir Thomas Poynings
• Margery, who before 1239 married Sir Giles Argentine and, secondly, Sir Jordan Sackville of Buckhurst
• Joan (died after 15 February 1263), who married Sir Ralph FitzBernard (their grandson was Bartholomew Badlesmere, 1st Baron Badlesmere)
• Agatha, who married Sir Adam Cockfield.[24]

From SGM by Chris Phillips, as below, on 29 Jul 2001:

These four daughters of Robert Aguillon seem to be bedevilled by genealogical confusion. Blomefield and others cite evidence suggesting that the daughter Margery's heir was Andrew de Sackville, said to be her son by Jordan de Sackville. But as argued on the web page, the evidence seems to be clear that her heir was Reginald de Argentein, her son by Giles de Argentein, and it seems impossible that she could even have been married to Jordan de Sackville. Margery's inheritance seems to have passed from Reginald de Argentein to Andrew de Sackville by a fine in c.1282
