John Underwood, deceased, was a native of Shelby County, Ky., born in 1795. He was married in his native county to Rebecca Radford, a native of Virginia, coming to Kentucky when a child. He came with his wife and six children to this township in the fall of 1835, having previously lived in Decatur County, Ind., nine years after leaving Kentucky. Mr. Underwood devoted his attention to the introduction of blue grass, and converting his lands into stock farming, he being the first man in the township to drive fat stock to market in Indianapolis. He died May 24, 1861, aged sixty-six years, his widow surviving him about six years. They were the parents of the following children--William, deceased; Mrs. Charlotte McMurry, of Normal, Ill.; Mrs. Elizabeth Carver, of Putnam County, Ind.; Mrs. Catherine Darnell, deceased; Mrs. Sally Soper, of Hendricks County, and Mrs. Ellen Bridges, deceased, the latter being the only one born in this county. Mr. Underwood owned, at the time of his death, a farm of 325 acres.
