Samantha is a feminine given name. Origins. The name was recorded in the 18th century in New England, but its etymology is uncertain. Speculation (without evidence) has suggested an origin from the masculine given name Samuel and anthos, the Greek word for "flower". One theory is that it was a feminine form of Samuel, to which the already existing feminine name Anthea was added. Popularity. "Samantha" remained a rare name until the 1873 publication of the first novel in a series by Marietta Holley, featuring the adventures of a woman named "Samantha," wife of Josiah Allen.
