Welson / Wilson

Welson is a surname-turned-given name, derived from the patronymic 'Wilson'. The name Wilson itself means 'son of Will', with 'Will' being a diminutive of William. William is a Germanic name composed of the elements 'wil' (will, desire) and 'helm' (helmet, protection). The practice of using surnames as first names became popular in English-speaking countries, particularly in the 19th and 20th centuries.

While Wilson is a very common surname and occasionally used as a first name, Welson is a much rarer variant. It likely emerged as a phonetic alteration or a less common spelling of Wilson, or perhaps through independent derivation from a less common form of 'Will'. Its rarity suggests it has not seen widespread adoption as a given name.
