Janece is of American origin, derived from the Latin name "Johannes," which means "God is gracious." It's a unique feminine variation of the male name John. The name gained popularity in the United States during the mid-20th century and has since been associated with a few notable individuals, such as Janece Blackburn, an American actress known for her role in the film "The Man from Earth" (2007).
Janece experienced fluctuations in popularity over the decades. The name's highest visibility was in the mid-1950s with peaks of 16 and 15 births in 1955 and 1956 respectively, indicating a brief trend during this period. However, it seems Janece never quite reached the level of other popular names from that era. The name's popularity declined significantly post-1960s, with the highest number of births in subsequent decades being only 18 (in 1992). From the 1970s onwards, there were several years with fewer than 5 births named Janece annually, suggesting rarity during this period. Overall, while Janece has had some periods of popularity, it remains a relatively uncommon name throughout the decades.
