John Carmi Parsons, in his article 'Eleanor of
Castille and the Countess Margaret of Ulster', _The Genealogists’ Magazine_ 20 (1982) 335–340.
He pointed out the unlikelihood that Richard de Burgh's wife Margaret was the daughter of a John de Burgh of Lanvallay - the elder of these men died in 1248 and 'can hardly have been father-in-law of a man born as late as 1259', while the younger did have a daughter named Margaret but she became a nun and did not receive a share with her sisters in the
Lanvallay inheritance.
The more probable, though unproven, link to the counts of Guines is taken from Pere Anselme, who stated that an unnamed daughter of Count Arnoul III by Alice de Coucy married an unidentified Irish lord.
In the article this information was not traced further - it came via _Histoire généalogique des maisons de Guines, d’Ardres, de Gand, et de
Coucy_ by André Duchesne from a 15th century genealogy of the families of Dreux and Coucy that is now in the Bibliothèque national in Paris.
