Family Note
Stewart Baldwin: 'No Irish source mentions ... the marriage of Radnailt to Cynan ap Iago. While it would be nice to have confirmation of these marriages in a more contemporary source, there does not seem to be any good reason to doubt them. The close connections of Gruffudd ap Cynan with Dublin are well documented.'

Stewart Baldwin: 'The name of the wife of Cynan ap Iago, her parentage, and her mother's parentage are known only from GaC (and sources dependant on GaC). Although reservations have sometimes been expressed regarding this information, enough of the data from the pedigrees of Radnaillt are verified in Irish sources that I am inclined to regard the information as genuine. For a recent discussion of this, see Seán Duffy, "Ostmen, Irish, and Welsh in the Eleventh Century", Peritia 9 (1995), 378-96.'
