Leonard, of Germanic origin, means 'brave lion'. It is derived from the elements 'leon' meaning 'lion', and 'hard' meaning 'strong, brave, hardy'. The name was introduced to Britain by the Normans in the form of Le Brun or Le Noir, which later evolved into Leonard. In literature, it's associated with characters like Dr. Leonard 'Bones' McCoy from Star Trek.
"The name Leonord experienced some fluctuations in popularity during those years, with a notable dip between 1916 and 1920, followed by a slight increase in 1931."
