The following is a quote from the History of Harrison County, Iowa: David E. Barnum, deceased, one of the pioneer band who found their way to Harrison County in 1854, claimed one hundred and sixty acres of land in Boyer Township, and in January, 1855, he built a frame house, which was built upon a basement, and during the hard winter of 1856-57 they occupied the basement. Mr. Barnum was born in Greene County, N. Y., June 8, 1834. He remained there until he was sixteen years of age, and then went to live with an uncle at Ft. Wayne, Ind. Five years later he came to Iowa; believing in that gracious saying that 'it is not good for man to be alone, he made the matrimonial proposition to a fair maiden of Harrison County, by the name of Lovinia Palmer, and September 21, 1856, the most charming season of the year, such proposition was accepted, for it was upon that day they were united in marriage. As a result of this marriage union, eleven other Barnum's came to dwell in their household and to be provided for by their tender watch-care. David E. Barnum, of whom this memoir is written, passed from earth June 14, 1890.
In the Harrison County Township Patrons Directory, 1884, D. E. Barnum is listed as having arrived in Woodbine, Boyer Township in 1854 from New York. He is shown as a farmer/stock raiser, with property in Section 23.
