Twylia, of Welsh origin, is an uncommon and unique given name for females. It means 'leader', derived from the Welsh word 'tweliad'. This name was popularized by the character Twyla in the 1960s film 'The Sound of Music'.
The name Twylia experienced its most popular years between 1961 and 1965, with a high of 11 births in 1962. After that peak, usage declined steadily, with only one year (1977) recording more than five births since then.
