Sometimes surnames prove to be more common in Cornwall than elsewhere, even though they look to be anything but Cornish. Waddleton is one. This was probably a local spelling for the surname Waddington, named after a number of places in northern England and in Surrey. The first Waddleton appears in 1744 in the Antony marriage registers. This location, across the river from Devonport, suggests a maritime route into Cornwall. By 1861 the name had ramified and dispersed as far west as Bodmin although most Waddletons remained in south-east Cornwall.
Walkam is no doubt a spelling variant of Wakeham or Wakem, which has its source in a place in south-west Devon. Present in mid-Cornwall from at least the 1540s, Wakehams dispersed widely across the territory. Around 1600, the variant Walkham began to make an appearance in east Cornwall and at Padstow. This surname in the main confined itself thereafter to a belt of country in mid-Cornwall to the north and east of St Austell.

Like Waddleton and Walkam, Watty is a rare surname these days. But unlike the others, it was very common in sixteenth-century Cornwall. Its numbers then gradually diminished over time. By the 1700s there were just relics of its former ubiquity – at St Ives and in mid-Cornwall around St Austell Bay.

The clue to the history of this surname, presumably a pet form of Watt, short for Walter, lies in its early geography. In the 1500s and 1600s it was entirely confined to the western, Cornish-speaking parts of Cornwall. It was also present on several occasions as one part of the three-part names that were a distinctive element of the Cornish language community’s naming culture. However, with the erosion of the Cornish language, the name lost popularity and probably fell together with Watts or Watt.
