Janson

Meaning & origin

Janson is a modern given name derived from a Dutch and Scandinavian patronymic surname meaning 'son of Jan.' It first appeared in U.S. birth records in 1958, but has remained uncommon, never breaking into the top 1,000 names. Its peak came in 2016, when it reached its highest rank to date, though it has been declining in use since 2017. In the most recent year of data, 2025, Janson ranked 5,399th, with a frequency of roughly 1 in every 100,475 newborn boys. The name fits the broader trend of using surnames as first names, particularly those ending in '-son,' and appeals to parents seeking a rare, distinctive name with a clear patronymic heritage. Janson is virtually never used for girls, as all recorded instances in Social Security data have been male.

Janson is a modern coinage derived from the common Dutch and Scandinavian surname Janson, which means 'son of Jan' (Jan being a variant of John). The surname itself arose as a patronymic across northern Europe. As a first name, Janson emerged in the United States in the mid-20th century, following the trend of using surnames as given names. It has never been common but has seen modest usage, particularly in the 2010s.
