Meaning and history
Latinized form of the Greek name Ἀγαθή (Agathe), derived from Greek ἀγαθός (agathos), meaning “good.” Saint Agatha was a 3rd-century martyr from Sicily who was tortured and killed after rejecting the advances of a Roman official, and she was widely revered in the Middle Ages, so her name was used throughout Christian Europe in various spellings. A famous modern bearer of the name was the mystery writer Agatha Christie (1890–1976).
Agatha rose from #924 to #914 for girls between 1941 and 1945. Its highest annual birth count came in 1918, with 218 births.
