Jeanice is of Latin origin, derived from the Latin word "Janus," which means "to open" or "gateway." It is a feminine variant of the male name Jean. The name gained popularity in France during the Middle Ages and was often used among French nobility. In English-speaking countries, Jeanice became more prevalent in the mid-20th century, with its peak of usage occurring between 1950 and 1960. Today, it is still a recognized name but has somewhat fallen out of fashion compared to other similar names like Jennifer or Jessica. The name Jeanice does not have any specific historical figures associated with it, nor are there any prominent literary characters named Jeanice that could influence its popularity. Despite this, Jeanice remains an attractive and unique choice for parents looking for a distinctive yet recognizable name for their daughter.
The name Jeanice had two peaks of popularity, occurring nearly four decades apart, with five babies being named Jeanice each year in 1943 and again in 1987.
