DeMoss
A surname most likely built from a French-style prefix plus a place- or nature-based root, though its exact origin is uncertain.
The #6,323 most common surname in the United States (2010 Census) — about 1 in every 57,186 Americans shares it.
Etymology
DeMoss is not a securely established surname in the major historical dictionaries, so its origin is best treated cautiously. It may be an Americanized or altered form with French-looking "de" plus a root resembling "moss," possibly referring to a mossy place or a local feature. In some families it may also reflect spelling variation from a longer Continental or Anglo-French name that was simplified after immigration or over time.
History
The surname appears in the United States in relatively modest numbers, which fits a name that may have undergone local spelling change rather than preserving a long standardized history. Without early documentary forms, it is difficult to tie it confidently to one homeland or surname family. In practice, DeMoss is often treated as a distinct American spelling, even if several older name forms may lie behind it.

Fun fact
Because the name is uncommon and not firmly documented in the older reference works, family lines may need to be traced through early census, church, and land records rather than surname dictionaries alone.
