Laesha is of African origin, derived from the Swahili word "lasha," which means "to laugh." This name is often associated with joy and positivity due to its connection to laughter. It gained popularity in English-speaking countries during the late 20th century but remains relatively uncommon. Laesha is typically given to females and can be spelled in various ways, including Lashae, Lasha, or even Leisha.
Laesha has seen a fluctuating popularity with peaks in 1985 and 2001, but it has generally maintained a steady presence since the early 1980s, with total births amounting to 34 over this period.
