The name Lesa is of Hawaiian origin and means "happy". It is believed to have been created by Princess Victoria Ka'iulani, who was born in 1875 and spent her early years in Hawaii before moving to England for her education. She is said to have invented the name Lesa as a shortened form of her own name, which would have been pronounced something like "Leh-sah" in Hawaiian. The name Lesa became popular among Hawaiian families after Princess Ka'iulani's time and continues to be used today.
Lesa is not a very common name in the United States. According to the available statistics, there were only 5 babies named Lesa born in the year 1961 and another 7 babies named Lesa born in the following year, 1962. This means that over these two years combined, there was a total of just 12 newborn girls given the name Lesa. This makes Lesa quite an uncommon name compared to many others used during this time period.
