Meaning & History
Doria is a feminine given name of modern English coinage. It is possibly a feminine form of Dorian or an elaboration of Dora. As a name used in English-speaking countries, Doria has only marginal recognition and appears to have been created through the addition of a feminine suffix.
Dorian, the underlying masculine name, was famously coined by Oscar Wilde for his 1891 novel The Picture of Dorian Gray. Wilde likely adapted the name from the ancient Greek tribe known as the Dorians, who were speakers of the Doric dialect. Through Wilde's literary creation, Dorian gained popularity as a first name in the 20th century, and from this, Doria emerged as a creative feminine counterpart.
