DAVID SEYMOUR BROWN.
David Seymour Brown, who owns and cultivates the northwest quarter of section 5, Munson township, his farm being improved according to the most modern methods of agriculture, was born in Allegheny county, Pennsylvania, February 26, 1862, and is a son of William T. and Mary (Neal) Brown. The parents came to Henry county when their son David was but two years of age and for a number of years afterward Mr. Brown cultivated a rented farm, while subsequently he lived for a time in Geneseo township. He afterward purchased eighty acres of land in Osco township, where he spent the remainder of his days. His entire life was devoted to general agricultural pursuits and he was a man of industry and perseverance, whose success was attributable entirely to his own labors. In the family were two children, but the elder, Margaret, died at the age of two years.
David Seymour Brown is indebted to the public school system of the county for the educational privileges which he enjoyed. Through the periods of vacation he worked in the fields and after his school days were over he devoted his entire time and attention to the improvement of the home farm until about thirty years of age. He was then married, on the 28th of January, 1892, to Miss Lora Gilbert, a daughter of Nathaniel C. and Francelia (Amsden) Gilbert. Her father was born near Richmond, Ontario county. New York, while the mother's birth occurred near Rochester, Vermont. It was in the year 1856
