Samuel H. Gill was appointed postmaster of the Pocahontas County town of Havelock on March 1, 1882. First mail service was provided by the postmaster’s twice-weekly horseback ride to and from Pocahontas, then via messenger from the nearby Chicago & Northwestern Railway stop. Eventually, train service was discontinued in favor of highway-based Star Route Service which originated from the Fort Dodge office. The Havelock Post Office has been in its current location since the late 1940s; the building previously served as the Farmers Savings Bank.
