LYLBORN, (Northamptonshire) to the N. E. of Hilmerton, near Dow-Bridge over the Avon, was anciently the manor and seat of the Camvils, who built a castle here, of which, it said, there are still some remains; and from whom it went by marriage, in the R. of K. John, to Thomas Ld. Astley. It is supposed to have been one of the Roman stations, by its situation on the Watling-Street, one of their highways, and by the pavements, trenches, ruins of walls and houses, hills for castles, hillocks for bastions, &c. at and near it; and particularly by the vestigia of a fort, at the mount called the Round-Hill.
