Meilir ap Rhiwallon - FYI - Dates & Children

This is from the about me section:

Darrell Wolcott states that Rhiwallon ap Cynfyn had no sons. The date of death is the same year as the Battle of Mynydd Carn, and this man may actually be Meilir ap Rhiwallon ap Gwyn ap Collwyn. Please see Darrell Wolcott: The Battle of Mynydd Carn; http://www.ancientwalesstudies.org/id35.html. As well as Trahaearn ap Caradog of Arwystli; http://www.ancientwalesstudies.org/id68.html. (Steven Ferry, July 7, 2020.)

But Bartrum thinks otherwise. As you know I favor Wolcott over Bartrum in most cases.
