Meaning & origin

Jeferson is a respelling of the more familiar Jefferson, a surname-turned-first-name with presidential pedigree. First recorded in U.S. data in 1997, the name saw its peak popularity in 2008. As of 2025, it ranks 5399, awarded to roughly 1 in every 100,475 newborn boys. Its trajectory appears stable, neither rapidly rising nor falling. The variant with one 'f' may reflect influence from Portuguese and Spanish orthography, where double letters are less typical. Jeferson remains a rare but recognizable alternative to the classic Jefferson.

Jeferson is a respelling of Jefferson, which derives from the English surname meaning 'son of Jeff'. Jeff is a diminutive of Geoffrey or Jeffrey, names of Germanic origin meaning 'peace' and 'territory'. The name Jefferson gained fame as a surname of U.S. President Thomas Jefferson. The variant Jeferson, with one 'f', emerged in the late 20th century, possibly influenced by Portuguese and Spanish naming patterns where the double 'f' is less common.
