They held no lordships. They had no titles - not even any knighthoods for personal achievements, per Shaw's Knights. Brason Head was a farm, not a manor, and the house was a farmhouse named after its elaborate brass door-knocker. (It is now in the British Museum.)
They appear to have been, at most, respectable and well-off members of the local squirearchy (untitled gentry).
