Coined by Marie Corelli in her 1887 novel; possibly from Greek thelema meaning 'will' or 'wish.'
Thelma owes its existence almost entirely to a single novel. In 1887, the wildly popular British author Marie Corelli published Thelma: A Society Novel, featuring a luminously beautiful Norwegian heroine whose name Corelli appears to have invented or adapted from the Greek thelema, meaning will, wish, or volition. The novel was a sensation, and within a decade Thelma had become a genuine given name on both sides of the Atlantic — a remarkable case of a single work of popular fiction seeding a name into common use almost from nothing.
Through the early twentieth century, Thelma climbed steadily in popularity, particularly in America and Britain, where it occupied a sweet spot between exotic and familiar. It attracted parents who wanted something distinctive but not outlandish, something with a faint Nordic romance. By the 1920s and 30s, it had become solidly mainstream, carried by actresses, socialites, and everyday women alike.
The name's association with feminine willfulness — built into its Greek etymology and amplified by Corelli's fierce heroine — gave it a subtle edge that other fashionable names of the era lacked. In 1991, Ridley Scott's Thelma & Louise electrified the name with new meaning. Geena Davis's Thelma Dickinson begins the film as a timid housewife and ends it as a defiant fugitive choosing freedom over surrender — the Greek thelema, will and volition, fully realized.
The film permanently altered the cultural resonance of the name, making it a shorthand for female solidarity and radical self-determination. Today Thelma sits in the vintage revival lane, beloved by parents drawn to names that carry genuine history and a little bit of fire.
