The name Oliviah, an orthographic variant of Olivia, derives from the Latin noun oliva (olive tree) and, by extension, evokes connotations of peace and dignity within Anglo-American onomastic traditions. Phonetically transcribed as /oʊˈlɪviə/, it was bestowed upon 13 newborn females in 2024, yielding a national ranking of 937 in the United States, and has exhibited rank oscillations between 889 and 953 from 2001 through 2024. Its adoption curve—punctuated by a temporal apex of 53 occurrences in 2011 and subsequent moderation—illustrates a stable yet measured parental preference for classical etymology coupled with distinctive orthographic modification. The terminal ‘h’ functions as a morphological differentiator without altering semantic content, thereby enhancing nominative uniqueness within contemporary registries while retaining intrinsic linkage to its prototypical Latin root.
