Marion R. Glassgow, a farmer of New Market, Taylor county, Iowa, who owns two hundred and forty acres of land in Dallas township, was born in this county, February 8, 1868, and is a son of William and Julia A. (Roberts) Glassgow.  The paternal grandfather, who like his son bore the name of William, was of Scotch descent and had a family of eight children: William, Samuel, Charles, David, Newton, James, Mattie and Bell.  The eldest, who is the father of the subject of this sketch, was born in Ohio.  During the four years of the Civil war he served with distinction to himself and to the honor of his country, as a member (page 578) of Company F, Twenty-ninth Iowa Infantry, and upon his return from service continued his work as a farmer.  Mrs. William Glassgow was born in Illinois and is a daughter of Ambrose Roberts and the sister of Warren, Daniel, James and Lorenzo Roberts.  She became the mother of five sons and two daughters, namely: Marion, Frank, George, John, Lola, Maria and William.
Marion R. Glassgow was reared at home on the farm under the guidance of his parents and received in the district school of his locality such formal preparation for life as could be gleaned through the short winter months it was in session.  During the summer months he assisted with the farm work, so that by the time he had attained manhood he was fully competent to manage a farm of his own and intelligently and skillfully cultivate a large tract of land.  Eight years ago he moved to his present farm, where with renewed energy he has carried on general farming and has engaged in stock raising and feeding.  He has been more than ordinarily successful in his work, his fields produce abundantly, and the stock is subject to perhaps fewer of the misfortunes that overtake the average cattle man.
On the 14th of January, 1892, Mr. Glassgow was married to Miss Belle Hunter, who was born in Henry county, Iowa, in 1873, and is the daughter of Giles and Jennie (Armstrong) Hunter, and a granddaughter of George Hunter.  She is one of a family of five children: Belle, Doudand, Ralph, John and Blaine.  To Mr. and Mrs. Glassgow have been born a family of four, who are still living, Allie, Essie, Edward and Ray, while Opal Belle died in infancy.
In political matters Mr. Glassgow gives his support to the republican party, for whose candidate he has never failed to cast his vote from the first time he could exercise his franchise as a citizen of this republic.  Though he is an advocate of good government, he has never sought public office for himself, finding his time fully occupied with his farming and stock interests and fully content with the returns they have brought him.
