Meaning & origin

Williom is an exceedingly rare alternate spelling of William, first recorded in 1915. Its peak usage occurred in 1931, though it never approached the popularity of William. The name has remained stable in its rare usage ever since. Williom does not appear in any top state rankings, suggesting it was used sporadically across the U.S. As a variant, it carries the heritage of William without the familiarity, making it a distinctive choice.

Williom appears to be a rare variant or misspelling of the established name William. William itself derives from the Old Norman French Willaume, from the Germanic elements wil 'will, desire' and helm 'helmet, protection'. Williom likely emerged in the early 20th century as an alternative spelling, but it never gained widespread usage.
