Leory is of French origin, derived from the Germanic 'Lothar', which means 'famous warrior'. It is composed of two elements: 'leud' meaning 'people' and 'hari' meaning 'army'. Leory was a popular name among the Franks during the Middle Ages. Today, it remains relatively uncommon, perhaps contributing to its distinctive charm.
The name Leory experienced fluctuating popularity throughout the early to mid-20th century. It peaked briefly with 15 births recorded in 1935, but generally hovered around 5-10 births per year between 1900 and 1971, with a total of 287 births during this period.
