Lenox is a unisex given name of American origin, derived from an Old English surname meaning 'from the woods'. It was traditionally used as a surname, but gained popularity as a first name in the late 20th century, particularly among families with Southern U.S. roots.
The name Lenox experienced a significant increase in popularity from the year 2005 onwards, with a notable spike starting around 2012 and continuing through to at least 2023. Prior to this period, the number of annual births with the name Lenox fluctuated between 5 and 16, with most years showing fewer than 10 births. However, from 2012 onwards, the number of births per year has consistently been above 40, reaching a peak of 170 in both 2022 and 2023. This data suggests that Lenox became considerably more popular as a baby name over this time frame.
