Modern invented name, likely a blend of Jay and Octavia.
Jatavia is a contemporary American name created by combining the popular prefix 'Ja-' with the rhythmic ending of Octavia. While it does not have a singular ancient root, it carries the legacy of the Latin name Octavia, meaning 'eighth'. It emerged in the late 20th century as part of a trend of melodic, multi-syllabic invented names.
