Deneise is of American origin, derived from the French 'Denyse', which itself is a feminine form of Denis. This name gained popularity in the United States during the mid-20th century, but its roots can be traced back to the Latin 'Dionysius', meaning 'following Dionysus'. The name Dionysus was a Greek god of wine, fertility, and pleasure. Deneise is often associated with the French cultural influence on American naming practices.
"The name Deneise was quite popular in the early to mid-1900s with a significant number of babies named each year between 1950 and 1972. However, its popularity waned towards the late 1960s and early 1970s, with only five or fewer births recorded per year from 1976 onwards."
