Sullins
An English surname most likely developed as a family-name variant of Sullivan or a related southern form of the same Gaelic root.
The #8,765 most common surname in the United States (2010 Census) — about 1 in every 82,530 Americans shares it.
Etymology
Sullins is generally understood as a variant surname form connected to Sullivan, which comes from the Irish Gaelic Ó Súileabháin. That older name is usually explained as meaning something like "descendant of Súileabhán," with the personal name commonly interpreted as a form related to "little dark-eyed one" or "one-eyed," though the exact sense is debated. In English records, spellings often shifted widely, and Sullins can reflect a phonetic or regional reshaping of Sullivan rather than a wholly separate source.
History
The surname is most often found in English-speaking records, especially in the United States, where immigrant names were frequently simplified or altered in spelling. Sullins is likely one of several Americanized or regional offshoots of the broader Sullivan name tradition. Because it is comparatively uncommon, it may also represent multiple local surname lines that converged on the same spelling.

Fun fact
Many uncommon surnames like Sullins survive because a family line fixed a spelling that began as one of several loose phonetic variants.
