Glenis, derived from the Scottish surname Glennis or the female given name Glenda, is a unique and charming name of Gaelic origin. It is composed of two elements: 'glen', meaning 'valley' in Scots and Scottish Gaelic, and 'is' or 'eis', which signifies 'peace'. Thus, Glenis can be interpreted as 'peaceful valley'. This name is not particularly common, making it distinctive and memorable. It gained some popularity during the mid-20th century but has since become quite rare, adding to its allure.
The name Glenis has seen varied popularity over the years, with peaks in the late 1920s and early 1930s, as well as a resurgence in the 1950s. However, it appears to have fallen out of favor more recently, with only five births recorded in 2020.
