Women certainly wore wooden-soled clogs with leather uppers such as those still made and sold in parts of Wales in the 1980s, but there is no evidence that they wore solid wooden clogs like those worn in Holland except for one illustration, by W.H. Pyne of Welsh washerwomen.
Large numbers of clog and pattern makers are recorded in the census returns for 1851 for the following counties: Pembrokeshire (50), Cardiganshire (48), Anglesey (20). In 1901, the numbers were significantly different: Carmarthenshire (79), Pembrokeshire (40), Cardiganshire (35), Radnorshire (11). Other parts of Britain with large numbers are Lancashire, Yorkshire, Cumberland, Dumfriesshire and Westmorland.
