Named after Alphonse de Lamartine, the French poet and historian, who sprang into such wonderful popularity during the French Revolution of 1848. Peter V. Sang, an organizer of the Seven Mile Creek Community, and then its postmaster and town clerk, circulated a petition to change the name of the town from Seven Mile Creek to Lamartine, in honor of the French revolutionary, whose works and political activity had been acknowledged by the United States Government on April 26, 1848, by formal diplomatic recognition. On June 13, 1848, a bill was offered to the First Wisconsin Legislature, to change the name of the community from Seven Mile Creek to Lamartine. The bill was passed and signed into law by Governor Nelson Dewey on August 8, 1848.
