Meaning & origin

Sebert is an exceedingly rare English name, given to fewer than 5 boys in the U.S. since records began in 1880. It was first recorded in 1915, its peak year with only 1 birth, and has seen no recorded usage in subsequent decades, making it virtually extinct in modern naming. The name likely derives from the Old English Sæberht, connecting it to early medieval royalty, but its rarity and lack of recent data place it firmly in the category of historical curiosities. With no occurrences after the 1910s and no top state affiliations, Sebert remains a footnote in American naming history.

Sebert is likely a variant of the Old English name Sæberht, composed of elements sæ (sea) or sige (victory) and beorht (bright). The name appears in early medieval England, including a 7th-century king of Essex, though its modern use is rare. It may also be a variant of Seibert or Siebert, Germanic names with similar meanings.
