Omara
A surname of Gaelic or Arabic appearance, most likely an Anglicized form of an older personal name or family name beginning with O' or Omar.
The #6,993 most common surname in the United States (2010 Census) — about 1 in every 64,429 Americans shares it.
Etymology
Omara is not a single, securely fixed surname origin in the absence of a historical citation. In Irish contexts, it may reflect an Anglicized form built on the O' prefix, meaning 'descendant of,' attached to a Gaelic personal name that was later simplified in spelling. In Arabic contexts, it can reflect a family name or patronymic based on Omar, a common given name meaning 'flourishing' or 'long-lived' in traditional interpretation.
History
Because the spelling is compact and relatively uncommon, Omara may arise independently in more than one naming tradition. In English-language records it can also appear as a simplified or adjusted spelling of Irish surnames beginning with O'Mara or of Arabic-derived family names. Its modern distribution in the United States likely reflects both Irish and Middle Eastern immigration streams.

Fun fact
The same spelling can plausibly point to different family histories, so one Omara line may be Irish while another is Arabic.
