Gourmaëlon or Wrmaelon (died 913/4), was the Count of Cornouaille and de facto ruler of Brittany from 907 – c. 914.
[1] As ruler of Brittany he was considered Prince de Bretagne in some chronicles and histories.
His actual history is among the least well documented of the early medieval rulers of Brittany.
He is believed to have been named Count of Cornouaille by Alan I, King of Brittany near the end of his reign in 907.
[4][b] His life and activities are sparsely recorded in historical documents save for several donations to the Breton churches of the day.
