Caister-on-Sea No. 1 / Castor Holy Trinity / Castre

There are two entries for Caister [variant spelling] in the Domesday survey [http://domesdaymap.co.uk/place/TG5112/caister/] [accessed 28 May 2014], neither of which mentions a church or cleric in it. Blomefield (1805-1810) writes: "The town was divided into 2 parishes, Castor Trinity, and Castor St. Edmund. Castor Holy Trinity church was a rectory, anciently valued at 30 marks, and the abbot of St. Bennet had a portion of tithe [...] In 1289, John occurs rector. [...] On the 8th of July 1387, Henry Bishop of Norwich appropriated this church to Shouldham priory, [...] On this appropriation, and a vicarage being settled, [...] At the dissolution of Shouldham priory, the rectory of this church, and patronage of the vicarage, was granted by King Henry VIII. on May 7, in his 36th year, to Sir William Paston. [...] 1608, Ralph Same, A.M. by Sir William Paston; this year, September, the church of the Trinity in Castre was consolidated to this of St. Edmund. [...] This church is decayed, and made use of as a barn." [NB: the time of Blomefield's writing was ca. 1750].
