Sigebert Buckley

Sigebert Buckley O.S.B. (c. 1520 – probably 1610) was a Catholic Benedictine monk in England, regarded by the English Benedictine Congregation as representing the continuity of the community's tradition through the English Reformation.

Although the English Benedictines had been dissolved by Henry VIII in the 1530s, a solitary monastery was re-established at Westminster Abbey by the Catholic Queen, Mary I of England in 1556 under John Feckenham. The monks were again ejected under Elizabeth I in 1559. By 1607, only one of the Westminster monks was left alive: Father Sigebert Buckley.

Buckley survived until the reign of James I, by which time a number of Englishmen had become Benedictines in the monasteries of Italy and Spain and had obtained a faculty from Pope Clement VIII in 1602 to take part with the secular clergy and the Jesuits in the English mission. It was through the efforts of the English monks of the Cassinese or Italian Congregation (including Thomas Preston) that Buckley became instrumental in preserving monastic continuity in England. It is through Buckley that the English Benedictine Congregation lays claim to an unbroken continuity with the pre-Reformation monasticism of England.

The Benedictine Ampleforth Abbey and Ampleforth College, the largest Roman Catholic boarding school in England, traces its history through Buckley.
