Please see Peter Bartrum: Hwfa 1; https://www.geni.com/documents/view?doc_id=6000000173393115835 [NOTE: Bartrum charts this line in his Hwfa series as an unconnected chart, based on Pen 134, 147 which ends "from Hwfa", but the line actually goes back to Hwfa ap Ithel Felyn, as Wolcott charts in Pedigree of Cynddelw Gam, cited above.] (Steven Ferry, November 15, 2023.)
