Maurice 1st Earl of Desmond; mother of Gerald the Poet, 3rd Earl (our line). This rung LOOPS the Desmond line onto the existing Ulster earls - a sister of our Kildare ancestress Joan de Burgh. Standard well-documented medieval genealogy per the cited authorities (web-confirmed 7 Aug 2026); contested rungs note-only, not hardened.
