The main street in Lawrence is called Massachusetts Street. Many early residents of Lawrence came because of the New England Emigrant Aid Company which was from Massachusetts. Streets that went north and south were named after US states in the order they became part of the country. Streets that go east and west were name after famous Revolutionary War heroes. Over time, people broke the first rule. Some states were never used, and some states were put in the wrong order. In 1913, the east and west streets became numbered streets.
