The location of this lordship is not certain but it seems likely it refers to a hill of the same name (meaning in Welsh "grey slope") between Penmachno and Ysbyty Ifan in Gwynedd.
The precise spelling of the name "Rhiw Llwyd" varies in historic documents, ranging from "Friw", "Friwllwyd", "Rhiwlwyd" and others.
Rhiw Llwyd is found within the ecclesiastical parish of Penmachno and is topped with a triangulation point.
The family seem to have owned Parc (their primary home) for a long time before they sold "Havodwryd".
The sisters of Richard were married and their families, Owen and Roberts, then owned Havodwryd thereafter.
