 The parish, in the 1530s, was unique in Wales in furnishing the title of a suffragan see, namely Bishop of Penrydd, and an Inventory of Ancient Monuments explains how this may have come about.The parish is marked (as "Penrith") on a 1578 parish map of Pembrokeshire.The parish church of St Cristiolus (Church in Wales) existed at least as early as 1799, the earliest date from which parish register information has been garnered.
