Jessalyn is a modern feminine given name of English origin. It is a combination of the name Jessie 1 and the popular name suffix -lyn, which is often derived from names like Lynn or elements meaning "lake" or "waterfall." This type of blending became fashionable in the 20th century, creating melodic and feminine names through the fusion of a short name or nickname with a trendy suffix. The first element, Jessie, originally emerged as a Scottish diminutive of Jean 2, but in modern times it is also used as a diminutive of Jessica. This dual heritage gives Jessalyn connections to both the traditional name John—through the ultimately derived Jane and its French forms—and the modern, literary name Jessica, popularized by Shakespeare's The Merchant of Venice. Notable Bearers While Jessalyn is a relatively uncommon name, it has been borne by several actresses: Jessalyn Gilsig (born 1971): Canadian actress known for her roles in television series such as Glee, Vikings, and Boston Public. Jessalyn Van Trump (1887–1939): American actress active in the silent film and early talkie eras. Jessalyn Wanlim (born 1982): Canadian actress and model, known for her role in the television series Orphan Black. All three have contributed to the name's public recognition without achieving extreme popularity.
