Ruaidri Dáll Ó Catháin
Rory Dall O’Cahan (Irish: Ruaidhrí Dall Ó Catháin) may have been an Irish harper and composer. Recent research, however, raises the question whether he ever really existed. He is said to have been born circa 1580 in County Antrim and to have died circa 1653 at Eglinton Castle.
