Laetitia is a feminine given name of Latin origin, derived from the Latin word 'laetus', which means 'happy' or 'joyful'. It was used by the ancient Romans to denote a state of joy or happiness. The name Laetitia gained popularity in France during the 18th century and has since been adopted internationally. In some variations, it may be spelled Laeticia or Letitia.
"Laetitia saw its popularity peak in the late 60s to early 70s, with over 10 births recorded annually between 1968 and 1974. However, it maintained consistent use throughout the century, with at least five births recorded every year since 1952."
