Please see Peter Bartrum: https://www.geni.com/documents/view?doc_id=6000000173392536826. Bartrum charts her as a daughter of Rhanallt, not Senena ferch Caradog. Note also that Bartrum charts her as a wife to a c. 1195 Maredudd ap Madog, but that is chronologically not feasible given her date estimate of c. 1240.(Steven Ferry, July 12, 2021.)
