Founded as the "Town of Strother", by William B. Howard for his wife, Maria D. Strother (daughter of William D. Strother formerly of Bardstown, Kentucky). Howard came to Jackson County in 1842 from Kentucky, married Maria in 1844, and by 1850 he and Maria had 833 acres (3.37 km2) and a homestead five miles (8 km) north of town. In 1865 the town of Strother changed its name for early settler Dr. Pleasant John Graves Lea, who moved to Jackson County in 1849, from Bradley County, Tennessee. Lea was listed as the postmaster of Big Cedar in the 1855 United States Official Postal Guide.When the surveyors for the Missouri Pacific Railroad came through, the local people and the railroad wanted to name the town in Dr. Lea's honor. He had a farm on the highest point and near the path of the tracks, and his murder had taken place near the site of the proposed depot. So they chose the name of "Lea's Summit", the "summit" portion to reflect its relatively highest elevation on the Missouri Pacific Railroad between St. Louis and Kansas City.But they misspelled the name "Lees Summit" (with two "e's"; "Lee" instead of "Lea"; and leaving out the apostrophe) on a boxcar that was serving as a station and donated by the Missouri Pacific, then a sign next to the tracks, and finally in the printed time schedule for the railroad.Since the name was already being circulated and published with two "e's", the town petitioned the state legislature and incorporated its name in 1868 as: "Town of Lee's Summit".
