Brian de Brompton...was stated by the Jurors of Stottesden Hundred, in 1292, to have appropriated three acres of the King's Fee in the Manor of Stottesden eight years previously. The value of the land was 1s. per annum. Brian had also, said the Jurors, enclosed two years previously a high-road which led from Chorley towards Strongeford, Kynlet, Kidderminster, and Worcester. As to the first charge, Brian replied that Stottesden was in possession of John de Segrave, who might sue him if he chose. As to the road, he said that a straighter and more convenient road was still open. This the Jurors denied. The old road was therefore ordered to be reopened, and Brian was in misericordia.
On December 28, 1294, Brian de Brompton, the last of the eldere male line of his House, was deceased. 1
