Manthorpe near Bourne is the only one of the three settlements called Manthorp(e) to be mentioned in the Domesday Book (Mannetorp). It was mentioned in conjunction with Witham-on-the Hill and Toft-with-Lound.

So far only one reference has been found to a person taking his name from Menethorpe: Hugh de Menethorpe, who was prebendary of Ulleskelf (which lies to the south-west of York, south of Tadcaster).

He was recorded between 1297 and 1301. There is no evidence at present of a Menethorpe family surviving after the medieval period.

Modern road maps show two Manthorpes in Lincolnshire and Menethorpe, a small village south of Malton in Yorkshire. None of these were parishes in the Middle Ages but instead outlying secondary settlements, as the "-thorpe" suffix implies.

Very few families can trace ancestors in the Middle Ages, apart from those descended from the nobility and gentry. This is an outline of 200 years of Manthorp history up to the middle of the 14th century.
