Meaning & origin

Bynum is an exceedingly rare given name, first recorded in 1899, the same year it reached its peak usage. It has never appeared in the top 1,000 names for any year, and its one-in-N ratio is too low to calculate. The name's trajectory has remained stable over decades, with no significant revival. As a surname transferred to the first name, it reflects a pattern common in the late 19th and early 20th centuries. Its top states show no concentration, suggesting scattered use. Bynum offers a distinctive choice for parents seeking a name with historical roots but little modern recognition.

Bynum is likely an anglicized form of an Irish surname, possibly Ó Beignigh or Mac Beignigh, though its exact derivation is uncertain. As a given name, it emerged in the late 19th century, often used as a surname transferred to the first name. It remains extremely rare, with its peak usage in 1899.
