Deloise

Meaning & origin

Deloise is a rare feminine name that first appeared in U.S. birth records in 1916. Its origins are unclear but it likely emerged as an American coinage, perhaps as a variant of Delores or a blend of De- and Louise. The name's use was concentrated in the mid-20th century, reaching its peak in 1953, though it never entered the top 1000 names. After the 1950s, usage declined sharply, and by the 2020s the name became exceedingly uncommon, with fewer than five births per year. The trajectory of Deloise remains stable but very low, reflecting its status as a name strongly associated with a specific era rather than a modern revival. No particular U.S. state has shown a notable concentration of the name, as its overall numbers are too small for reliable state-level data.

Deloise first appeared in the early 20th century United States, possibly as a feminine elaboration of the given name Deloy or as a variant of Dolores or Delores. It may also have been coined from the common prefix De- combined with Louise. The name saw modest but consistent use from the 1910s through the 1960s, with its peak in 1953, though it never reached the top 1000.
