   Another name for Èttiene was Stephen I Count of Brittany.

  General Notes:

~Weis' Ancestral Roots. . ., 119:26, 214:24, 214A:24, 227:24, identifies him as count of Brittany, Trèguier and the holder of the honour of Richmond, in England, founder of Augustinian abbey of Ste. croix at Guincamp, abt. 1110, founder of Cistercian abbey of Begard, m. Hawise who was living in 1135. ¹⁶⁰

~ Cokayne's Complete Peerage, 1st Edition, 1895, Stephen was the youngest of Eudes' eight legitimate sons (His older brothers being Geoffrey Boterel I, Brian, Alain "the red", Alain "the black", william, Robert, and Richard). There is no express evidence that Stephen was the son of Orguen/Agnes, and he may have been the issue of a second [i.e. an unknown] marriage.
He succeeded his oldest brother, Geoffrey (or possibly Geoffrey's son, Conan) in his Breton lands and another brother, Alan "the black" in the honor of Richmond in England, thus uniting all the possessions of the family, but he appears to have been out of the possession of the honor of Richmond for a time during the reign of King William II.
In 1101, he was a surety for King Henry I for the observance of an alliance with Robert II, Count of Flanders. ⁸⁵⁰

Èttiene married Havoise de Bretagne ¹⁶⁰.^,850 (Havoise de Bretagne was born about 1068 in Bretagne, France and died after 1136 in Bretagne, France ¹⁶⁰.)
