Isolde de Mortimer - Was Iseult a Bohun?

John Ravilious over at soc.genealogy.medieval recently suggested that Iseult / Isolde, wife of Hugh de Audley, might have been a Bohun rather than a Mortimer. The Mortimer connection is suggested by tenure at Arley, while a Bohun connection is suggested by her younger son's use of Bohun swan badge as a crest.
