Dorn
Usually a surname from a word for a thorn or thorn-bush, though some early writers suggested other origins in other languages.
The #3,502 most common surname in the United States (2010 Census) — about 1 in every 30,251 Americans shares it.
Etymology
The strongest historical explanation is that Dorn comes from a Germanic word for a thorn or thorn-bush, giving it the sense of someone who lived by, or was identified with, thorny ground or a thorn tree. An older source also notes Dutch as a possible origin with the meaning 'thorn-tree.' Because similar-looking forms occur in several languages, 19th-century writers sometimes proposed other etymologies as well, but the thorn derivation is the clearest and most widely supported.
History
The name appears in English-language surname discussions mainly as a continental name, especially German or Dutch in shape and meaning. Later reference works often gloss it simply as 'thorn,' which suggests a habitational or descriptive surname rather than a patronymic. In modern usage it remains relatively uncommon in the United States.
