Any thoughts on the Caudill surname?

[ThistleDown]

Black records the Cadell name as a form of Calder. 'The Northern Cawdors were disguised as Cadells and de Cadella even in old Scots chroniclers, and they have kept that variety permanently in the South.' He notes the name variously spelled as Cadell, Caddell, Cawdale, Calder, Cattall, Caldaile, Cadall, and that the name was common in Edinburgh in the 16C. Caudill is likely another spelling. In the late 18C the head of the name acquired property near Cockenzie in East Lothian and built Cockenzie House. The property is no longer in the family.
