This Welsh name means Rhiwallon son of Cynfyn.

Rhiwallon ap Cynfyn (c. 1020 – c. 1070) was an 11th-century Welsh King and co-ruler of the kingdoms of Gwynedd and Powys from 1063 to 1070.^[2][3] The son of Cynfyn ap Gwerstan and brother of King Bleddyn of Powys. Through his mother Angharad, he was half-brother to King Gruffydd ap Llywelyn as well. Following the 1063 invasion of Wales by Harold and Tostig Godwinson that overthrew Gruffydd, Rhiwallon and Bleddyn jointly received Powys and Gwynedd on condition of faithfully serving Edward the Confessor "everywhere by water and by land".
