In the hundred of Amounderness the Great Survey only refers to three churches, and these, though not named, were undoubtedly Preston, Kirkham, and St. Michael's-on-Wyre; and in the absence of proof to the contrary we must assume that none others were then in existence, though possibly others may have been erected in Saxon times, but, like the district upon which they stood, were then lying waste (see p. 57). Poulton is dedicated to St. Chad (a Saxon saint), and Garstang may possibly have been the site of a pre-Conquest church, although its proximity to St. Michael's renders it somewhat improbable. Preston Church was originally dedicated to St. Wilfrid, and was probably built in the tenth century; Kirkham,[181] or the church village, may even be of an earlier foundation than Preston, for from the time that Roger de Poictou granted the church to St. Mary of Lancaster (see p. 187) to the present date its history is clear and fairly complete; no trace of the Saxon building has, however, been discovered. At St. Michael's, also, all material evidence of the pre-Norman period has long ago disappeared. In Amounderness only two religious houses were established--one at Preston, the other at Lytham. At Preston was a Franciscan convent of Grey Friars, or Friars Minor, built in 1221 by Edmund, Earl of Lancaster. Within the precincts of this house was buried Sir Robert Holland, who impeached Thomas, Earl of Lancaster of treason. Little is known concerning this friary; in 1379 letters were addressed to the Warden of the order of Preaching Friars there, asking them to pray for the Duke of Lancaster on his going abroad. There was also at Preston a hospital for lepers, which must have been established early in the twelfth century, as Henry II. took it under his protection, as did also King John; there was a chapel attached dedicated to St. Mary Magdalen. The cell at Lytham was dependent upon the Priors of Durham from its foundation in 1190 to 1443, when it became partly independent. They were black monks. In the hundred of Leyland no churches are mentioned in Domesday Book, but there was almost certainly one at Croston and another at Eccleston, as both these were given to the priory of Lancaster in 1090 (see p. 187), and if not in existence at the taking of the Survey one can scarcely avoid coming to the conclusion that long before that date churches had been erected at Eccleston, Leyland and Standish, the latter being dedicated, like Preston, to St. Wilfrid.
