Thomas de Hibernia should not be confused with Thomas of Ireland.
Thomas de Hibernia (fl. 1270) was an Irish theologian. Said to be a native of Palmerstown, County Kildare, he became a Franciscan, and Fellow of Sorbonne, Paris. In later life, he moved to Italy, dying ca. 1296 in the "Convent of Aquila, in the Province of Penin." On his death-bed he bequeathed his books and papers to the Sorbonne, "together with six pounds for the purpose of purchasing a rent to celebrate his anniversary."
Lampen, a Franciscan, argues that Thomas Palmeranus, Thomas Hibernicus and Thomas Palmerstonus are the same person.
