The attractive village of Manthorpe near Grantham was first mentioned in 1185 and again in 1212, but was not a parish in the Middle Ages.

The pretty little church with its apple-green pews was built in the 19th century, and the village itself was the scene of the Manthorpe gathering in 1992.

During the Middle Ages a local family took its name from this settlement. The documentary references read:

1242-3 - Ranulf de Maunetorp holds in Maunetorp the fifth part of a knight's fee of Nicholas de Lundertorp and the same Nicholas of Roger de Hungoldby and he of the barony of Clinton.
(Book of Fees, No 1034. Lundertorp is Londonthorpe, also near Grantham.)

24 June 1314 - John de Maldon complained that Alan Talebot and John his son, Walter de Manthorpe and Thomas son of Thomas de Kirkeby cut his corn growing at Kirkeby by Leythorpe (Kirkby la Thorpe) Co. Lincoln and carried it away.

(Kirkby la Thorpe is somewhat closer to Grantham than Bourne, so Walter probably belonged to the Grantham family)

The 1332 lay subsidy for Lincolnshire lists William de Manthorp assessed at 2s 5d, and Gilbert de Manthorp assessed at 2s in Londonthorpe and Towthorpe (near Grantham)
