The name Densil, of Welsh origin, is derived from the element 'dinas' meaning fortress, and the suffix '-l', suggesting a patronymic form. It was traditionally used as a boys' name but can also be used for girls. The name has been relatively rare throughout history, adding to its uniqueness. Notable figures with this name include Densil Prince, a British actor known for his role in the film 'The Elephant Man'. The name Densil is often associated with strength and resilience due to its fortress-like origin.
"Despite its uncommon nature, the name Densil experienced periodic popularity between 1915 and 1963, with peak years being 1922, 1923, 1925, and 1943, each having 8 or more births. However, it appears that this popularity did not sustain over time, as the total number of births declined steadily after the 1960s."
