Dillon Beach is named after George Dillon, an Irish immigrant who settled in the area and built a hotel in 1859. The village was planned by John Keegan, who purchased land from Dillon in 1903, and was developed by Sylvester Lawson and his sons in 1923. The Lawson family still inhabits the area, running Lawson's Landing, a popular camping and RV park, as well as other local farms and businesses.
Seaglass was built in 1925 by the Hennigan family and stayed in that family until 2004.
