The Benedictine Abbey of Saint Mary at Winchcombe was a major medieval religious landholder in Gloucestershire and surrounding counties. It held Adminton from at least the Domesday period and recovered the manor after its temporary assignment to Saint-Evroult before its own dissolution.

Institutional holder rather than an individual person.
