• Wikitree: Riwallon (Poher) de Poher (778–857).

Medlands: Brittany: Dukes of Brittany

• a) ERISPOË (-murdered [2/12] Nov 857, bur Redon). Regino names "filius Nomenoi Herispoius" when recording that he succeeded his father in Brittany[10]. The Chronica Fontanellensis names "Respogio filio Nomenoi, tyranno Brittonum"[11]. The Chronica Rainaldi records that "Rainaldo…comite Nannetensium" was killed in 843 while fighting "Herispoium, Noremoi filium at alios Britannos apud Metiacum"[12]. "Erispoius…provinciæ Brittaniæ princeps" names "genitoris mei Nominoe…consobrini mei Salomonis filiique mei Conan episcoporumque" in a charter dated 19 May [851/57][13]. He succeeded his father in 851 as Duke of Brittany. Although "Respogius filius Nomenogii" swore allegiance to Charles II "le Chauve" King of the West Franks, he defeated the king's army at Jengland, on the river Vilaine, and was ceded Rennes, Nantes and the pays de Retz[14], although peace was agreed and confirmed by the betrothal of Erispoë's daughter to the king's son. The Annales Bertiniani record that "Respogius dux Brittonum" was killed in 857 by "Salamone et Almaro Brittonibus"[15]. The Chronica Rainaldi records that "Herispoius rex tyrannicus Britonum" was killed in 857 by "Salomone" [his cousin][16].
• m MARMOHEC, daughter of --- (-[856/57]). The Chronicle of Nantes records a donation by "Herispogii" for the soul of "Marmohec coniugis nostræ" dated 857[17], which suggests that she was then deceased. No indication has been found that Marmohec was the mother of Erispoë's children who are shown below.
• Erispoë & [his wife] had three children:
  • i) daughter. ... Betrothed (Feb 856, contract broken end 857) to LOUIS, son of CHARLES II "le Chauve" – [but did not marry Loise 'le Débonnaire'. She may be the same dau. as below.]
  • ii) daughter. [She may be the same dau. as above,] m ([after 857]) GURWENT [Gurvand], son of ---....
    • {The author of a fr.Wikipédia article for Marmohec believes there was only one daughter. trans. "[Marmohec] gave two children to Erispoi: a son, Conan and then an anonymous daughter who, after being engaged by her father to Prince Louis the Begeu, son of Charles the Bald, would have married Gurwant, 'Earl of Rennes' and 'cousin of Salomon'."
  • iii) CONAN (-after 857). "Erispoius…provinciæ Brittaniæ princeps" names "genitoris mei Nominoe…consobrini mei Salomonis filiique mei Conan episcoporumque" in a charter dated 19 May [851/57][23]. The Chronicle of Nantes records a donation by "Herispogii" for the soul of "Marmohec coniugis nostræ" dated 857 subscribed by "Konani…", signing first in the list of subscriptions but without any indication of his relationship to the donor[24].
• NOTE: FMG mentions No parentage because there is No primary source showing Riwallon III or NN. Lahngau as Marmoëc's parents. The singular, very brief Wikipédia about her (above-link) does not postulate on parentage. The second and final sentence does postulate that she had another son: "Contemporary sources indicate only that she is the mother of the princeps Judicael". (citing Chronique de Réginon de Prüm : AD 874. “Judicheel ex filia Herispoii regis natus”)
