Meaning & origin

Deloria is a distinctive modern name that first appeared in the United States around 1921, during a period when inventive blends and elaborations were fashionable. Its highest popularity came in 1936, when it was given to roughly 10 baby girls per million, but it has been extremely rare ever since. The name's trajectory has remained stable at very low usage over the past century, never cracking the top 1000. While its exact etymology is unknown, it likely draws from the sounds of established names like Delores and Dora. Deloria has never been associated with any top states, reflecting its scattered occurrence. For parents seeking an uncommon name with a vintage feel, Deloria offers a unique option without a strongly defined meaning.

Deloria is a rare modern coinage that first appeared in the United States in the 1920s. It may be a combination of the popular name Delores (from Spanish Dolores, 'sorrows') and Dora (a short form of Dorothy, 'gift of God'), or an elaboration of Delia. Its peak usage was in 1936, but it has since become extremely uncommon.
