Of the three names below Bastard most obviously originated in a nickname. As might be expected, it was found over a wide area in the 1500s.
Bariball probably developed from the name Barbarel, introduced by the Normans and present in the 1300s in Devon, where it’s been suggested it was from a nickname. Or did it come from the first name Barbara?
The most obscure is Basher. Only two examples are found in the 1500s, and these widely seperated. There is also a possible Annis Bashe at Sancreed in West Penwith in 1582 although the reading is unclear. To deepen the mystery further it then disappears for over a century before popping up again on the Lizard.
You can find maps of these names in 1861 for comparison here.
