Odum
A surname with more than one possible origin, most likely from a place name or an old nickname-based form.
The #7,585 most common surname in the United States (2010 Census) — about 1 in every 70,474 Americans shares it.
Etymology
Odum is usually treated as a surname of uncertain origin. In English surname patterns, it may be a reduced or altered form of an older place-name surname, or a nickname-based name that shifted in spelling over time. The exact root is not securely established from standard surname evidence, so any literal meaning should be treated cautiously.
History
The surname is found chiefly in English-speaking countries, especially the United States. In America it is most familiar in the South, where many surnames with older English or British Isles roots became established early and later spread through migration. Because the name is not strongly documented in the major older surname dictionaries, its history is best described as local and uncertain rather than tied to a single well-known origin story.

Fun fact
Odum is uncommon enough that family lines can sometimes be traced in local records more easily than through broad surname histories.
