Blackmon
An English-style surname that likely began as a nickname or variant spelling built on Black- plus a second element that may have been reshaped over time.
The #1,628 most common surname in the United States (2010 Census) — about 1 in every 13,951 Americans shares it.
Etymology
Blackmon is most likely an English surname, but its exact origin is not securely established from the available evidence. It appears to be formed with black-, a very common surname element used for someone with dark hair, a dark complexion, or occasionally a darker association in place names or nicknames. The second element may reflect an older surname pattern that has been altered by spelling simplification or local pronunciation, so the name is best treated as uncertain rather than as a straightforward compound with a fixed literal meaning.
History
The surname is established in the United States and is especially visible in southern records, but the excerpted historical source does not provide a firm derivation. Some Blackmon families may descend from earlier English or British surnames that changed spelling after migration, while others may reflect independent local formation. Because the documentary trail is thin and later spellings vary, the name is often discussed cautiously by onomastic references.
