Research notes
✓ Brut; Lloyd: BLEDDYN AP CYNFYN (d.1075), law-reviser; father of Maredudd (our line). ||RESEARCH-FLAG|| FRONTIER-ish: father Cynfyn ap Gwerystan + royal mother Angharad ferch Maredudd ~ NOTE-ONLY - the pedigree-tract edge, treated as at Egbert. Added 14 Sep 2026. STATUS CLARIFIED same day: Bleddyn himself and the two filiations BELOW him (Maredudd, Madog) are contemporary-chronicle attested (Brut y Tywysogyon; Lloyd read first-hand) - the FRONTIER flag on this record refers ONLY to his own parents ABOVE, where the pedigree tracts begin. Do not re-flag the man as unverified; the flag marks where verification ends, not that it is absent.
