Meaning & origin

Seith is an uncommon American given name first recorded in 1978. Its usage has remained very low, and it did not rank among the top 1000 names in any year. The peak year for Seith was 1999, after which its frequency has remained stable at a very low level. Since the name has no clear historical or cultural roots, it likely emerged as a modern spelling variant of Seth, possibly influenced by surname usage. Its rarity means that fewer than 5 boys per year receive this name in the United States, and it has never been concentrated in any particular state.

Seith does not have a well-documented historical etymology. It may have originated as a modern spelling variant of Seth, a Hebrew name meaning 'appointed' or 'placed', though the connection is speculative. Alternatively, it could be derived from an English surname, itself of uncertain origin. The name has been used sparingly in the United States since the late 20th century, first recorded in 1978, with a peak in 1999.
