The noble Breton family line of Porhoët is represented in modern times by the Franco-Breton House of Rohan.

History

The first recognised Vicomte de Porhoët was Guithenoc (abt. 990-1040CE), was born in Guilliers. He married Allurum (994-?) of Guilliers. He became Vicomte, and in about 1008 he moved to La Trinite, in Porhoet. Both Guilliers and Porhoet are located in the modern day French departement of Morbihan in the province of Brittany.

In Porhoët Guithenoc built Josselin Castle, which he named for his son, Josselin (1020–1074). It is still owned by the descendents of Porhoët and is the longest continuously held private estate in the world.

Vicomte Josselin de Porhoët had three sons with the surname Rohan: Mainguy De Rohan, Jostho de Rohan, and Roger de Rohan. He had a fourth son, the third vicomte de Porhoët, Eudo I de Porhoët (1049-?).

Eudo (or Eudes) I married Anne de Leon (1065-?). They had two children, Vicomte Geoffrey de Porhoët (1092–1141) and Alain I de Rohan

Geoffrey is said to have married Hawisa Fergant of Brittany (abt. 1105-?). They had two sons, one of which was as Odo II or Odo, Viscount of Porhoët (1122-?).
