In approximately 1730, a number of Scotch-Irish settled in a part of the town called Hunter's Settlement.[3] Martin's Creek was first settled by Robert Lyle in 1741, with James Martin arriving around 1747. Martin operated a grist mill, and later served as a colonel in the American Revolution. In 1744, missionary David Brainerd began his work here with the Clistowackin band of Lenape Indians.[4]
By the 1800s, the area had developed the name of Flatfield because of its level terrain. By the time of the Civil War, it was known as Martinsville, and later changed to Martin's Creek.
In 1939, exiled Russian prime minister Alexander Kerensky married Australian journalist Lydia Ellen Tritton in Martins Creek.[5]
In 1942, an explosion at the Lehigh Portland Cement Co. plant in nearby Sandts Eddy killed 31 people.[6] The Hunter-Martin Settlement Museum commemorates the early history of the area.
The major industry in the area was as the Alpha Portland Cement Company, which closed in 1964.[7]
