Cozart
A surname most likely representing a regional or altered form of an older name, rather than a word with a clear standalone meaning.
The #7,585 most common surname in the United States (2010 Census) — about 1 in every 70,474 Americans shares it.
Etymology
Cozart is best treated as a surname of uncertain origin, probably arising as a spelling variant or regional reshaping of an older English name. It may ultimately reflect a place-name, a nickname, or a different surname that shifted in pronunciation and spelling over time. Because the documented forms are sparse and not securely tied to one root, a precise literal meaning cannot be stated with confidence.
History
The surname is found mainly in the United States, where it likely spread through families whose name had already changed form before or during immigration and internal migration. In many such cases, local spelling habits and clerical record-keeping helped stabilize a newer surname form. The name is uncommon enough that its history is difficult to trace from broad surname dictionaries alone.
