Priors of Christ Church Priory included John of Sittingbourne (elected 1222, previously a monk of the priory) and William Chillenden, (elected 1264, previously monk and treasurer of the priory). The monastery was granted the right to elect their own prior if the seat was vacant by the pope, and – from Gregory IX onwards – the right to a free election (though with the archbishop overseeing their choice). Monks of the priory have included Æthelric I, Æthelric II, Walter d'Eynsham, Reginald fitz Jocelin (admitted as a confrater shortly before his death), Nigel de Longchamps and Ernulf. The monks often put forward candidates for Archbishop of Canterbury, either from among their number or outside, since the archbishop was nominally their abbot, but this could lead to clashes with the king or pope should they put forward a different man – examples are the elections of Baldwin of Forde and Thomas Cobham.
