Guihomar I, Viscount of Léon

Guihomar I of Léon was one of the first Viscounts of Léon. He lived c. 1021 - 1055 and is said to be the son of a certain Alan of Léon or more probably a descendant of a legendary Count Even.

He is cited in 1021 and in 1034 or 1040. He is said to have owned estates in the Kemenet-Héboé in the Bishopric of Cornouaille. This rise in power threatened Alain Canhiart, the Count of Cornouailles, who was victorious in 1055 and gave the hamlet of Lezugar en Beuzec to the episcopal authority. Guihomar I was still alive at the time .

Guihomar is said to have had a son named Éhuarn but according to Joëlle Quaghebeur Ehuarn was actually a “Viscount from Cornouaille”, that is to say of a Viscount of Le Faou who married a woman belonging to the House of Léon.

He was undoubtedly succeeded by his supposed grandson and namesake Guihomar II as Viscount of Léon .
