Erispoë II, king of Brittany - Erespoe I vs Erespoe II

This bit has me somewhat confused. Erespoe II born circa 794, married to Marmoec de Poher; son of Nominoe born circa 790; son of Erespoe I born circa 775, also married to a Marmoec de Poher. So, which Erespoe was married to Marmoec, and what are the correct approx birthdates? (I assume Nominoe did not father a child when he was 4 years old.)

775-812 Erispoe I is father to Nomonie and Rawaillon. Nomonie is father to Erispoe II who married Marmoec, who is his first cousin, dau of Rawallon. Nomonie and Rawallon could have had a Maromec as their mother ( names are given to many relatives and carried down) Take all dates as about/circa. some the numbers are transposed.
