Danna
A surname that may be a shortened or altered form related to Irish names such as Danaher/Daniher, though the exact origin is uncertain.
The #8,458 most common surname in the United States (2010 Census) — about 1 in every 79,084 Americans shares it.
Etymology
The available historical excerpt does not give a direct entry for Danna, but it places the name beside Irish surnames such as Danaher and Daniher. That makes it plausible that Danna is a shortened, altered, or simplified form ultimately connected with an Irish surname tradition rather than a separate medieval name of its own. Because the evidence is indirect, the exact root and literal meaning cannot be stated with confidence.
History
The name appears to be relatively uncommon and may have arisen through spelling simplification or Anglicization in records outside Ireland. In modern usage it is found in the United States, but the historical documentation here is too thin to trace a single definitive line of descent.

Fun fact
In older surname dictionaries, Danna is not always treated as a stand-alone headword; it may appear only in lists of related forms, which is one reason its origin is hard to pin down.
