Welsh diminutive of Elisabeth, from Hebrew Elisheva — god is my oath. One of the Welsh names that spread across the whole of Britain in the 1970s and 1980s.
Bethan was given to 11 babies in England and Wales in 2025. Its best year was 1996, with 825 registrations. The name is absent from American records, so there is no US curve to compare it against.
