 At New Radnor, the town corporation controlled the creation of freemen, but the Steward of the King's Manors had the corresponding power at Knighton, Rhayader and Knucklas.These two sources of power competed with the other main landed interest, that of the Price family, for domination of Radnor elections in the 18th century, but it was the Steward who generally got his way.Henry Lewis was steward from 1746 until his death in 1768 and his brother, Thomas Lewis, was MP from 1715 to 1761 (when he was defeated because of technical errors in the registration of the freemen that supported him).
