Harmon surname meaning

Harmon is chiefly an English surname from the Norman and Middle English personal name Herman, built from Germanic elements for “army” and “man.” The same personal name underlies German Hermann and Harmann, so some American Harmon families are Americanized immigrant forms rather than English medieval lines. Harman, Herman, and Hermann are neighboring spellings, not proof of common descent. Parent’s name is the high-confidence catalog type: Harmon preserves an ancestor’s given name. The army-man gloss explains that older personal name; it is not a statement about a modern bearer’s occupation.
