From Wikipedia - Ramon Berenguer II, Count of Barcelona :

Ramon Berenguer II the Towhead or Cap de estopes[1][2] (1053 or 1054 - December 5 , 1082 ) was Count of Barcelona from 1076 until his death. He ruled jointly with his twin brother Berenguer Ramon II .

He succeeded his father Ramon Berenguer I, Count of Barcelona to co-rule with his twin brother Berenguer Ramon, in 1075.

The twins failed to agree and divided their possessions between them, against the will of their late father. Ramon Berenguer the Towhead, called so because of the thickness and colour of his hair, was killed while hunting in the woods in 1082. His brother, who went on to become the sole ruler of Catalonia , was credited by popular opinion of having orchestrated this murder. Berenguer Ramon the Fratricide was later succeeded by Ramon Berenguer's son Ramon Berenguer III .
