William O'Brien
O'Brien disagreed with the establishment of a southern Irish Free State under the Treaty, still believing that Partition of Ireland was too high a price to pay for partial independence. He wrote in 1923, "It is now obvious enough that, had the Irish Council Bill been allowed to pass in 1907, the Partition of Ireland would never have been heard of." Retiring from political life, he contented himself with writing and declined Éamon de Valera's offer to stand for Fianna Fáil in the 1927 general election. He died suddenly on 25 February 1928 while on a visit to London with his wife at the age of 75. His remains rest in Mallow, and one of the principal streets in the town bears his name to this day. His head-bust overlooks the town Council's Chamber Room and one of his finest portraits hangs in University College Cork.
Edward O'Bryen
Rear-Admiral Edward O'Bryen (sometimes O'Brien) ("c." 1753 – 18 December 1808) was a British Royal Navy officer prominent in the late eighteenth century, who is best known for his participation at the Nore Mutiny and the Battle of Camperdown, both in 1797 during the French Revolutionary Wars. At the Nore, O'Bryen had recently been given command of the ship of the line when the mutiny broke out. Although he was not the cause and the crew expressed their affection for him, O'Bryen had to be prevented from throwing himself overboard when his men refused to obey his orders. Just five months later, now in command of Vice-Admiral Richard Onslow's flagship , O'Bryen led the southern division of the British attack at the Battle of Camperdown, in which a Dutch fleet was destroyed and British supremacy in the North Sea confirmed. Although he was praised for his exertions in the battle, O'Bryen's health was deteriorating and he retired from the Navy in 1803, dying at the rank of rear-admiral five years later.
