In 1801, the population was recorded as 168. By the census in 1841, it had grown to 398. Before 1897 it was known as "Hestlewelle" or "Hesselwelle". Its growth was started by wealthy merchants from Liverpool; they had originally chosen it as a retreat, but the arrival of two railway connections allowed them to commute. One line is the Borderlands Line from Wrexham Central to Bidston which opened in 1896. This line is still active and has Heswall railway station on the eastern edge of the town. The station was formerly called Heswall Hills to distinguish it from the older, now demolished, Heswall Station. The old station was in Station Road in the Lower Village on another line from West Kirby to Hooton. This opened in 1886 but the line closed to passengers in 1956. The track of the old railway became a footpath, the Wirral Way.
