Seabolt
A likely English surname built from "sea" plus a place-name or dialect word resembling "bolt," probably originally describing someone from a coastal place or using a local name element.
The #8,743 most common surname in the United States (2010 Census) — about 1 in every 82,288 Americans shares it.
Etymology
Seabolt is most likely an English surname formed from the element "sea" combined with a second element that may reflect a local place-name, dialect word, or older surname form with the sound of "bolt." In many cases like this, the name can be tied to a coastal or seafaring association, or to a lost or altered place-name rather than a transparent everyday phrase. Because no historical dictionary entry was available here, the exact root cannot be stated with confidence.
History
The surname is comparatively uncommon and is found mainly in the United States today, where many such surnames came through English, Scottish, or German-speaking immigrant lines and then changed spelling over time. The form may also reflect anglicization or simplification of an earlier surname that sounded similar.

Fun fact
Names that look straightforward at first glance are often the hardest to pin down, because a modern spelling can hide a much older place-name or a heavily altered immigrant surname.
