The Grosvenor family first settled in the United States in 1650, in Pomfret, CT. Ebenezer Grosvenor was born on January 26th, 1820, to the parents of Ebenezer and Mary (Livermore) Grosvenor in Stillwater, NY. His parental grandfather was a Presbyterian minister and chaplain in the Army of Revolution, while his maternal grandfather was a solider at the Battle of Bunker Hill. Mr. Grosvenor moved first to Albion, MI in 1837 where he was a clerk in a local store. In either late 1838 or early 1839 he moved to Monroe, MI where he worked in the construction office of the Michigan Southern Railroad. In 1840, Mr. Grosvenor moved to Jonesville, MI where he worked as a clerk in the dry goods store owned by Henry Delaran and Elisha Champlin, a member of the Michigan Territorial Legislature and Southern Michigan pioneer. On February 22, 1844, Mr. Grosvenor married Miss Sarah Ann Champlin, the daughter of Elisha Champlin. The couple would go on to have only one child, Harriet, who would later marry Charles White, a local businessman. Following Mr. Grosvenor’s marriage in 1844, he would go on to use his life savings to become a partner in a general store. This would be the beginning of building his significant business empire. In 1854, Mr. Grosvenor was a partner in the founding of what quickly became the Grosvenor Savings Bank, now known as the Jonesville branch of County National Bank, and was the president of the bank until his death in 1910. His business interests also include being a merchant miller, acquiring large farming interests, and a primary stockholder in a number of other business and financial interests. While Mr. Grosvenor was a shrewd businessman, he was also very active in Republican Party politics. In 1858 and 1862 he was elected to serve in the Michigan State Senate. With the outbreak of the Civil War in 1861, he was appointed a Colonel on the staff of Governor Austin Blair and named President of the Military Contract Board and was later appointed President of the State Military Board. In 1864, he was elected Michigan’s Lieutenant- Governor and was elected State Treasurer in 1866 and 1868. In 1871, he was appointed vice-president of the Board of State Building Commissioners, which was then tasked to oversee the building of the new Michigan State Capitol. In 1879, he was elected to serve as a Regent of the University of Michigan. Even though Mr. Grosvenor was elected to serve in several state offices, he was also committed to remain active in local politics. He served for over thirty years in various positions for both the Village of Jonesville and Fayette Township. Committed to education Mr. Grosvenor spent forty-one years as a member of the Jonesville Board of Education and several years as a member of the Hillsdale College Board of Trustees. Ebenezer Oliver Grosvenor died on March 19, 1010 and Sally Ann Grosvenor died on July 6, 1910.
