She was Owain Gwynedd's first cousin, and therefore their marriage was prohibited by the church, but even when Owain was threatened with excommunication, he refused to put her aside.

RAGNALD (-killed in battle Tynwald 1228, bur St Mary of Furness). The Chronicon Manniæ et Insularum names “Reginaldum, Olavum et Yvarum” as the three sons of King Godred, adding that their father had nominated his legitimate son Olav as his successor, but that the Manxmen chose Ragnald as king because he was older[1302]. The birth date of his daughter, wife of the Welsh princes, indicates that Ragnald must have been much older than his legitimate half-brother. King of Man. The Chronicon Manniæ et Insularum records that Olav recovered Man from his half-brother in 1226[1303]. "Ragdnaldus…rex Insularum" donated "totam medietatem terre…Ormeshan…apud portum de Corna et aciam terram Asmundertoftes" to St Bees by undated charter, witnessed by "…Gospatricio filio Henrici…"[1304]. The Chronicon Manniæ et Insularum records that Olav was murdered in 1228 and buried at St Mary of Furness[1305]. m ---, daughter of --. Her parentage is confirmed by the Chronicon Manniæ et Insularum which records that King Ragnald arranged the marriage of his half-brother Olav to “filiam cujusdam nobilis de Kentyre germanam uxoris suæ, nomine Jauon”[1306]. ["the daughter of a nobleman of Kentyre a sister of his wife, namely Jauon". Sharon Doubell July 2021] Ragnald [& his wife] had four children:

i) daughter ([1182/83]-after 17 Feb 1205). Her parentage, betrothals and two marriages are confirmed by the following documents. Pope Innocent III, by letter dated 24 Nov 1199, requested an enquiry after “R. princeps Norwaliæ” requested permission to marry “filiam...prinicipis Insularum” notwithstanding that “patruo eius eadem infra nubiles annos exstitit desponsata”, in particular investigating whether she was still under 7 years old [youngest canonical age for marriage at the time] when “a nepote, vel patruo desponsata”[1307]. Pope Innocent III, by letter dated 19 Apr 1203, reported the enquiry after “N. princeps Norwalliæ” requested permission to marry “filiam...principis Insularum”, referring to his previous letter, confirming that “L. principe Norwalliæ” had been betrothed to “puella, completis octo annis”, that she was later betrothed to “patruo...suo”, that the enquiry found against the marriage but allowed it to stand to bring peace to the dispute[1308]. Pope Innocent III issued a third letter dated 17 Feb 1205, after further facts emerged, annulling the marriage and recording that “ejusdem L. patruus ipsam” was betrothed to the girl when in her ninth year, married her in her tenth, and cohabited with her, including “in Manniam rediens” before returning “in Walliam” by himself leaving his wife behind, for 2 years, 2 months and 15 days since their marriage[1309]. Her marriage date suggests that she was much older than her sister who married Thomas of Galloway. Maybe they were born from different marriages. Remfry notes that Dwnn’s Visitation incorrectly names “Rhunallt, the daughter of the king of Man” as wife of Gruffydd ap Llywelyn (see the document WALES) and suggests that this may represent confusion with the first/second wife of Llywelyn[1310]. m firstly ([1191/92]%29 RHODRI ap Owain Lord of Anglesey, son of OWAIN King of Gwynedd & his second wife Christina of Deheubarth (-[1194/95]). m secondly (Betrothed [1190]?, betrothal terminated [1191/92]), [1195/96], separated [annulled] [1203/05]) as his [first/second] wife, LLYWELYN ap Iorwerth Fawr ("the Great") Prince of North Wales, son of IORWERTH "Drwyndwyn/flat nose" Prince of Gwynedd & his wife Marared of Powys ([1173]-11 Apr 1240, bur Aberconway).
