Gwendalin, of Welsh origin, is derived from the elements 'gwen' meaning 'fair, white, blessed', and 'dylan' which means 'sea, tide'. This unique name gained prominence during the Middle Ages but has since become relatively rare. It was popularized by notable figures such as Gwendalin Davies, a renowned Welsh harpist and composer.
Gwendolin had an equal number of babies each year with a gap in 2006, resulting in a total of 15 births over those four years.
