Oceguera
A Spanish-language surname of likely regional origin, probably tied to a place name or local nickname rather than a clearly transparent everyday word.
The #9,081 most common surname in the United States (2010 Census) — about 1 in every 85,786 Americans shares it.
Etymology
Oceguera appears to be a Spanish surname, but its exact derivation is not securely established from standard onomastic patterns alone. It may be a locative surname formed from a place-name or a regional term that has since become obscure. Because the name is relatively uncommon, the original root is not easy to recover with confidence from modern evidence.
History
The surname is found in Spanish-speaking communities and is especially visible in Mexico and among Mexican-American families in the United States. Like many less-common surnames, it likely passed through local family lines with spelling stabilization only after migration and civil registration. Its present distribution suggests a Hispanic origin, but not enough evidence survives in general reference works to pin down a single source place or meaning.

Fun fact
In many Spanish surnames, initial letters such as O- and Ose-/Oce- can reflect older local spellings that later diverged by region and family line.
