Camborne never existed as a town at all in the middle ages. Probably Penponds, and Treswithian ('Jethan) as large villages supplied the congregation of the church. Possibly small hamlets also lay around the church and at Higher and Lower Rosewarne. We get all indication of this from a valuation of the Lands of Penwith, (Exchequer Q.R. Lay Subsidies,) soon after 1500: here William Bree (Bray) of Treswithian is returned as worth £200 in goods, quite the richest man in the parish...
At one time these De Brays or Brays, an ancient family even then beginning to decline, had held all the lands between the sea and Penponds, Nancemellan and Rosewarne ; but the last Bray (Arthur Bray), living at Treswithian, as at his death, in about 1700*, possessed only of Kieve Mill and a few fields above. Nothing but one possible worked stone fragment is left of the old house. 2
* Arthur Bray died in 1713.
