The Pirate Queen...
Sibeal is the Irish/ Gaelic version of Elizabeth and means “God is my oath.” It is also spelled Sybil, Cybil, and even Isabel. Sibeal is not a name brought up in ancient Irish history or mythology, but here is a story about a famous Irish woman who was admired by Queen Elizabeth I.
The Pirate Queen Grace O'Malley, also known as Granuaile and by her Irish Gaelic name Grainne Ni Mhaille, is one of Ireland's foremost heroines, whose life was the stuff of Irish legend.
Grace O'Malley's extraordinary life centers around the 16th century Tudor conquest of Ireland under Queen Elizabeth I. Grace was the daughter of the O'Malley clan chieftain who controlled the southwest of County Mayo and its coast from their castle on Clare Island. They were a renowned seafaring family who controlled the sea routes along the west coast of Ireland and charged a tax to fishermen and traders.
In 1546 Grace was married at a young age to the head of the O'Flaherty Clan, but when he was killed in battle, Grace became the head of the O'Flaherty's as well. Grace later remarried another powerful Irish Chief, Richard Burke, but divorced him after one year under the ancient Brehon Laws and got to keep his title and Rockfleet Castle near Newport in Co. Mayo.
As England steadily gained control of Ireland, Grace came under increasing pressure to relent to the English crown. An expedition from Galway attacked Grace in her castle on Clare Island, so Grace turned to piracy, blockading the port of Galway and attacking English ships in Galway Bay.
When the English governor of Connaught, Sir Richard Bingham, captured Grace O'Malley's two sons, she set sail for England to speak to Queen Elizabeth I face to face. Her ships sailed up the River Thames in London, where Grace met Queen Elizabeth at Greenwich.
On meeting the Queen, Grace refused to bow, stating that she herself was a Queen of her land and not a subject of the Queen of England. The two, who were roughly the same age, admired each other, and reached a truce. Grace would stop attacking English ships and start attacking Spanish ones, and her sons were returned to her.
