Tylyn is a unique and appealing given name of recent origin, deriving from the Welsh word 'tylwyth' which means "crowd" or "multitude". It is often mistaken for an anglicized version of the Welsh male name Tywysog, meaning "prince", but its etymology is distinct. This name gained popularity in the latter half of the 20th century and has since been used for both boys and girls, making it unisex. Despite its unisex nature, Tylyn tends to be more commonly encountered as a female name in recent years. The spelling variation Typlyn also exists but is less prevalent than Tylyn. The name's unique sound and Welsh origins make it an attractive choice for parents seeking distinctive names for their children.
"Tylyn experienced peak popularity in the early to mid-90s, with a significant spike of 46 births in 1993. After that decade, usage fluctuated but remained consistently low."
