Meaning & origin
Delmus first appeared in U.S. birth records in 1907, which remains its peak year of usage. The name has never ranked in the top 1000 and shows a stable, extremely low frequency over time, with no recorded births in the most recent year checked (2025). Its rarity places it well outside the 1-in-N naming range, meaning fewer than 1 in 100,000 newborns receive this name. Top states where Delmus was reported include none, as usage was scattered and well below the threshold for state-level reporting. The name likely originated as a variant of the more common Delmer, itself derived from an English surname. Despite its obscurity, Delmus carries a distinctly vintage, early 1900s character that might appeal to parents seeking a truly uncommon name with an authentic historical footprint.
Delmus appears in early 20th century U.S. records, likely as a variant of Delmer (from an English surname, itself perhaps from a place name). It may also have been coined by combining the common initial syllable 'Del' (as in Delbert, Delmar) with the masculine-sounding ending 'mus'. The name saw peak use in 1907 and has remained rare since.
