https://en.wikipedia.org/wiki/Stephen,_Count_of_Tr%C3%A9guier
Stephen of Penthièvre, Count of Tréguier, 3rd Lord of Richmond (1058/62- 21 April 
1136)[1] was a Breton noble and a younger son of Odo, Count of Penthièvre and 
Agnes of Cornouaille, sister of Hoël II, Duke of Brittany. In 1093, he succeeded to the 
title of Count of Tréguier; in 1098, he succeeded his brother Alain as Lord of 
Richmond in Yorkshire, England.[2]
Life[edit]

He is sometimes misidentified as "Stephen, Count of Brittany" in the court documents 
of King Henry I. This is likely due to his Breton heritage, when in fact at the time 
Brittany was a Duchy ruled by Alan IV, Duke of Brittany.

Stephen was a benefactor of religious houses. In 1110, he and his wife, Hawise 
founded the Augustine Abbey of St Croix in Guingamp. On an unknown date, he is 
recorded as having donated property to Rumbaugh Priory for the souls of his wife and 
children.[3]

He was the paternal grandfather of Conan IV, Duke of Brittany.

III, Count of Blois and Adele of Valois.[4] Their children were:

Matilda during The Anarchy.

Brittany, by whom he had issue, including his heir Conan IV, Duke of Brittany. Alan is
