WILLIAM HENRY O’DRISCOLL, Esq., of Stoke, near Plymouth. He was born on the 16th of June, 1803, and, though a fine specimen of the old Irish chieftain race, he is still unmarried. The senior line of the O’Driscolls is, therefore, likely to become extinct in the British Islands, and the genealogist of the next century will probably have to look for it in the United States of America: though, according to a wild tradition in the country, there are fishermen on Cape Clear and on other islands off the Coast of Carbery, who are lineally descended from the youngest son of Sir Finghin, or Florence, of 1602. The Rev. James O’Driscoll, P.P. of Kilmichael in the County of Cork, is said to be the great-grandson of Denis O’Driscoll of Dunbeacon Castle, who is remembered by tradition for his skill in performing on the Irish harp, who was the son of Florence O’Driscoll, called the Captain Cam, who was killed at the siege of Dunboy in 1602. Sed cum de his nihil certi scio, nihil etiam assertive determino.

There is a death recorded by will of 1764 of Patrick Driscoll Moulroe, parish of Schul just next to Dunbeacon.  Probably a man of substance in view of will.
