Europeans first settled the Haverhill area in 1640, colonists from Newbury following the Merrimack River in from the coast. The area that would become Lawrence was then part of Methuen and Andover. The first settlement came in 1655 with the establishment of a blockhouse in Shawsheen Fields, now South Lawrence.
