Combination of Jessica and Lynn
Jeslyn is a modern American blend, likely created by combining the Hebrew-derived Jessica, meaning 'behold' or 'wealthy', with the English suffix Lynn, meaning 'lake' or 'waterfall'. It emerged as part of the late 20th-century trend of creating melodic, multi-syllabic names using established phonetic components.
