Henrietta is a feminine given name of German origin, derived from the Teutonic 'henri', meaning 'home ruler'. It was popular during the Middle Ages but has since fallen out of common usage in many countries. Notable individuals bearing this name include Henrietta Maria of France, who became the wife of King Charles I of England, and Henrietta Lacks, whose cancer cells were taken without her knowledge or consent, leading to significant medical advancements.
The name Henrietta saw a consistent but not overwhelming presence throughout the late 19th and early to mid-20th centuries, with peaks occurring between 1892 and 1930.
