Land at Dalby was given to the Knights Hospitaller by Robert de Beaumont, 2nd Earl of Leicester (1104 – 5 April 1168) in return for other land.

[2] Before 1199 the Hospitallers had gained lands at Isley Walton, Heather, Ravenstone and Swinford, as well as gaining the advowsons of the churches of Ashby Parva, Buckminster, Old Dalby and Swinford, before 1220.

[1] Around 1338, Heather Preceptory came under the control of Dalby as a "camera", a lesser establishment dependent upon another.

Dalby seems to have taken the leading role, as it was where the joint preceptory was administered from and where the Preceptor was based.

[3] Rothley Preceptory was similarly merged with Dalby before 1371.
