Mixon
A surname most likely from a place-name or a shortened nickname-based form, with spelling shaped by English and American usage.
The #2,894 most common surname in the United States (2010 Census) — about 1 in every 24,911 Americans shares it.
Etymology
Mixon is most likely an English surname, but its exact origin is not entirely certain. In many cases it is treated as a variant spelling of names built from a personal name or a place-name ending in -son or -ton/-don that has shifted over time in speech and spelling. The surname may also have been influenced by local pronunciation and later spelling simplification in English-speaking countries.
History
The surname is best known in the United States, where it is found especially in the South and among families with long-standing Anglo-American roots. Like many surnames with variable spellings, it likely stabilized only after families had already moved between regions and clerks recorded the name in different ways. A few well-known modern bearers have helped keep the name visible, but it has never been especially common.

Fun fact
