Leofwine of Nuneham Courtenay held a manor of 5 hides here both before the Conquest and in 1086. The manor also included a mill and meadow for 2 ploughs. A second manor, of 2 hides with meadow for 2 ploughs, was held by Wulfric, a man of Aelfric son of Goding, before the Conquest and by Turstin from Walter Giffard in 1086. Turstin also held a third manor, also from Walter Giffard. This was assessed at 4 hides with meadow for 4 ploughs. Before the Conquest it was held as 3 manors by Aelfric son of Goding, Eadric, a man of Esger the staller and Saeward, a man of Azur son of Toti. At this time the vill was simply called Mortone. The 15thc church is traditionally believed to have been built by two maiden sisters of the Peover family, daughters of the last male heir, hence the prefix.
The parish is now in the Buckingham North benefice, i.e. Akeley, Leckhampstead, Lillingstone Dayrell, Lillingstone Lovell and Maids Moreton.
