The duty known as soca faldae is the duty of seeking the lords fold.
A similar expression is applied to the possession of 'soca'.
We must start with this that soke, socna, soca, is the Anglo-Saxon scn and has for its primary meaning a seeking.
The text says that he must lie at his lords fold; but probably it refers to the soca faldae.
Fragments of a sodalite-syenite have also been found at soca in the same neighbourhood.
