Research Notes:
the name of the wife of Cynan at Iago, her parentage, and her mother's parentage are known only from _Hanes Gruggudd ap Cynan_ of which the earliest manuscript is mid-13th century; although reservations have been sometimes express regarding this information, enough of the data from the pedigrees of Radnillt are verified in Irish sources that I am inclined to regard the information as genuine.
