SIBTHORPE, a parish in the southern division of the wapentake of NEWARK, county of NOTTINGHAM, 6 miles (S.S.W.) from Newark, containing 142 inhabitants. The living is a donative, in the patronage of the Duke of Portland. The church, dedicated to St. Peter, was originally much larger than it is at present: the north and south aisles have been taken down, so that the pillars and lofty arches of the nave are now worked into the outer wall of the building. In the reign of Edward II., Thomas de Sibthorpe founded a chantry in the church, and subsequently erected it into a college for a warden, nine chaplains, three clerks, and four choristers; he also added four chapels, in honour of St. Anne, St, Katharine, St. Margaret, and St. Mary; the revenue, at the dissolution, was estimated at £31. 1. 2. Thomas Seeker, D. D., Archbishop of Canterbury, was born here in 1693; he died in 1768.
