The Congregation founded daughter-houses such as that at
Furness Abbey and
Calder Abbey, both in
Cumbria,
England. In 1119, Pope
Celestine II, then in
Angers, took it under his immediate protection, and strongly commended it to the neighbouring nobles. Under Geoffroy, successor to Vitalis,
Henry I of England, established and generously endowed twenty-nine monasteries of this Congregation in his dominions. Early in the 12th century,
Buckfast Abbey was incorporated into the Benedictine Congregation of Savigny. The monasteries of
Basingwerk (Flintshire) and Neath (Glamorgan) in Wales were founded as Savigniac houses, as was
Combermere Abbey.
St. Mary's Abbey, Dublin was founded as a Benedictine house in 862, and given to the Congregation of Savigny in 1139. From the number of its foundations Savigny became the head of a Congregation, numbering thirty-three subordinate houses, within thirty years of its own inception.
Saint Bernard of
Cîteaux also held them in high esteem, and it was at his request that their monks, in the troubled times of the
Antipope Anacletus II, declared in favour of Pope
Innocent II. ==Administrative merger with the Cistercians==
