John Warburton was not included in the original 1886 Civil War data that was transcribed by Roseanna Zehner. In 2010 it was brought to light by Linda Linn that he was indeed in the Civil War (reference the following biography of his son shown below).

Biography of WILLIAM WARBURTON

Throughout his active business life, William Warburton was identified with the agricultural interests of Iowa and at the time of his death, which occurred December 9, 1913, was living upon his fine farm of two hundred and forty acres in Lakeville township, Dickinson county. He was born in England on the 12th of March 1852, and was a son of John and Mary (Gibson) Warburton, also natives of England. On the emigration of the family to America they located at Cresco, Howard County, Iowa, and in that locality the father engaged in preaching as a Methodist minister up to the time of his death. During the Civil War, however, he manifested his loyalty to his adopted country by enlisting in Captain T. W. Burdick's company, Sixth Iowa Cavalry, with which he served for three years, and was made chaplain of his regiment. When hostilities ceased he returned to his home in Cresco, where he died May 21, 1867. His wife, who was born December 25, 1815, passed away in February 1895.

It was during his boyhood that William Warburton became a resident of Howard County, Iowa, where he was reared and educated, and he remained with his mother until twenty-seven years of age. He was then married and located on a farm in Howard County, which he operated for sixteen years. In 1895 he came to Dickinson County and purchased two hundred and forty acres of land in Lakeville township, upon which he made many useful and valuable improvements. There he spent the remainder of his life and as previously stated passed away December 9, 1913, after three years illness.

On the 15th of March, 1879, Mr. Warburton was united in marriage to Miss Bessie Clink, a daughter of Joseph and Jane (Stewart) Clink, who were natives of Scotland and came to the new world at an early day, locating in Janesville, Wisconsin. There the father followed farming for some time and subsequently removed to Howard county, Iowa, where he died in April 1907. His wife had departed this life on the 28th of December 1903. The children born to Mr. and Mrs. Warburton are Gaylord, a farmer of Dickinson county; Fred and Frank both residents of Milford; Jeanie, at home with her mother, and Marietta, the wife of F. J. Hemphill, a farmer of Dickinson county.

Mr. Warburton supported the Republican Party at the polls and for several years served as road supervisor and also as school director. He was an earnest and consistent member of the Methodist church, to which his widow also belongs, and he had the respect and confidence of all who knew him on account of his honorable, upright life.
