Leona is the feminine of Leon and Leo — from the Latin leo, meaning "lion." Leona means literally "lioness."
Leona was popular in the early 20th century, peaked at #189 in 1925, and faded. It has been returning in the 2010s. The British singer Leona Lewis (born 1985) and the New York hotelier Leona Helmsley (1920-2007) are notable bearers. Today Leona sits in the U.S. top 500.
Leona reduces to six — the number of fierce maternal love.
