Glendalys is a unique and beautiful name of Welsh origin, meaning 'valley of the glen'. It is composed of two elements: 'glen', which refers to a narrow valley between hills, and 'dlys', an obscure element possibly derived from Dylan, a popular Welsh male name meaning 'sea wave'. This feminine form of Glendower, it was likely created as part of the Romantic trend for Celtic-inspired baby names in the 19th century. Today, Glendalys remains a rare yet enchanting choice for parents seeking an exceptional name for their daughter.
"Glendalys saw an even split of births over these years, with six babies each in both 1979 and 1983, making a total of twelve."
