MARION BAKER, merchant, Lone Tree; was born in Cedar county, Iowa, January 10, 1843. Is a son of Nathaniel Baker, who came to Iowa from Ohio in 1836. Martin Baker, grandfather to the subject oe this sketch, was the first preacher in the central and western part of the Blackhawk purchase, and held the first meeting in his cabin in July, 1836, near where Rochester is now situated. Never before had the sound of prayer and praise broken the stillness of the forest, unless it was the songs of the birds that was offered as a tribute to the glory of the Great Architect. Marion's father being a druggist, he also learned that business, and has since followed it exclusively until the last few years. In 1877 he came to Pleasant Valley township and lived on his farm one year, but owned a store in Lone Tree in partnership with his brother, and moved here in 1878, and has since bought out his brother and is now carrying a fine stock of dry goods, groceries and drugs, and is also engaged in the sale of agricultural implements, and still owns 130 acres of well improved land. He was married October 10, 1867, to Sarah E. Harding, of Keokuk, Iowa. They have five children: H. Ulysses, Carrie R., Proctor T., Preeda N. and Cecil H. Mr. and Mrs. Baker are members of the Reform Church.
