Abbeys in the U.K:

Newhouse was the first to be founded (1143) (BARNES) and was the parent of Dale and 10 others (C41E).   It had 11 daughter foundations between 1148 and 1200 (C/WC).  Wendling was the last (CLARK, C/WC).

Abbeys were mostly founded by feudal magnates, notably Ranulf de Glanville (founded Coverham, Langdon, W.Dereham, Welbeck and Leiston);  2 (Alnwick and Lavendon) were founded within sight of the castles of 1st ranking barons.

Each abbot owed obedience to the superior of the house from which his own had been founded.  The system to some extent reconciled centralisation and flexibility (C41E).

Tree of the foundation of the English abbeys, from C/WC, does not mention:
Brodholme abortive foundation
Irford Priory
Kalend abortive foundation
Dodford abortive foundation, between Holme Lacy (Hereford) and Halesowen
Guyzance abortive foundation
Holywood Abbey
Soulseat Abbey
Tongueland Abbey
Whithorn Abbey.
It does, however, show Hornby Priory NE of Cockersand.
Details of these houses are in C/WC.

It was cheaper to found a Premonstratensian Abbey than a Benedictine or an Augustinian, because the former wanted only rough land on which to pasture sheep.  Some were rich (e.g. Leiston, Torre, Halesowen and Titchfield) but some were inadequately endowed (e.g. Egglestone, Tupholm and Wendling) (C/WC).

Monasticism was popular because of political chaos and insecurity under Stephen.  Waverley, Tintern, Rievaulx and Fountains were founded under Henry I, and Savigny had 10 houses by Stephen’s time.  ‘Only half a dozen Cistercian abbeys were founded in England during the second half of the 12th century, the period during which nearly all the English houses of white canons were established’ (C/WC).
