Trusty
A nickname surname from Middle English/Old English meaning “faithful” or “reliable.”
The #7,950 most common surname in the United States (2010 Census) — about 1 in every 74,164 Americans shares it.
Etymology
Trusty is a nickname surname taken from the adjective meaning “faithful,” “loyal,” or “worthy of trust.” The word goes back to Old English and related Germanic forms built on the idea of trust, firmness, or faithfulness. In surname use, it would have begun as a descriptive label for someone known for reliability or steadfast character.
History
Surname forms from positive personal qualities are quite common in English, and Trusty fits that pattern. The historical sources here treat it directly as the ordinary word “trusty,” rather than as a place-name or occupational surname. It appears in American records as a relatively uncommon but established surname.
