Great Brickhill was described in 1806 in Magna Britannia as follows:
Great-Brickhill, in the hundred and deanery of Newport, lies about two miles and a half to the south-east of Fenny Stratford. The manor was anciently in the Beauchamps, from whom it passed by female heirs to the Bassets and Greys. Richard Grey, Earl of Kent, sold it in 1514 to Sir Charles Somerset, of whose son, Sir George it was purchased in 1549, by the Duncombes: from this family it passed, by female heirs, to the Bartons and Paunceforts, and is now the property of Philip Duncombe Pauncefort esq.
The manor of Smewnes-Grange, in this parish, became the property of Woburn Abbey, in 1293. King Edward VI granted it to Edward Stanton esq. of whose descendant it was purchased in 1792, (under an act of parliament which had passed the preceding year,) by the present proprietor, Edward Hanmer esq. of Stockgrove. This manor extends into the parish of Soulbury: the manor-house, which was built by Edward Stanton, the grantee, within a moated site near the River Ouzel, has long been suffered to go to decay.In the parish church are memorials of the families of Duncombe, Barton, Pauncefort, and Chase. The advowson of the rectory is annexed to the manor. This parish was inclosed by an act of parliament, passed in 1776, when an allotment of land was assigned to the rector, in lieu of tithes, and an allotment to the poor in lieu of their right of cutting furze.
