Valmore is of French origin, derived from the Occitan name 'Guauelm' or 'Guallem'. It was borne by Guillaume de Machaut (c.1300-1377), a French poet and composer, who popularized this form of the name. Valmore is composed of two elements: 'val', meaning 'strength', and 'mor', signifying 'dark or black'. Thus, it translates to 'strong as night' or 'strong and dark'. The name has been used sparingly throughout history but remains unique and distinctive.
"The name Valmore peaked in popularity between 1915 and 1923, with the highest number of births recorded in 1923 at 12. After a decline in the late 1920s and early 1930s, there was a resurgence in the mid-1930s, with a spike to 14 births in 1937. However, it appears that the name Valmore became less common after World War II, with only a handful of births recorded each year from 1942 onwards."
