HANS HANSEN.
Among the foreign-born citizens of Clinton county who have achieved well-merited success in life is Hans Hansen, one of the leading farmers and stock raisers of Orange township, his home being on section 15. He was born in Schleswig, Germany, June 1, 1840. and during his boyhood he received a fair education in the German language, while his knowledge of English has been self-acquired since coming to this country. He served one year in the Danish army. Before leaving his native land he was united in marriage, in 1863, with Miss Mary Jensen, and he there worked on a farm for some years.
In 1868, accompanied by his wife and three children, Mr. Hansen came to the United States, sailing from Hamburg to New York. On landing in this country he proceeded at once to Davenport, Iowa, and located near that city, where he worked at am thing which he could find to do for the first two or three years. In 1870 he rented a small farm and turned his attention to agricultural pursuits. In-March, 1874, he came to Clinton county, and after operating a rented farm for a year he bought a farm of one hundred and sixty acres in Orange t( uvnship, on which a small shanty had already been built. This he improved, making it his home for several years, while he devoted his time and energies to the further improvement and cultivation of his farm. He fenced and tiled the place, set out fruit trees and erected a barn and outbuildings. He resided there until 1885, when he bought one hundred and fifty-six acres of land, where he now resides and has since added to it an adjoining tract of twenty-seven acres, making a good farm of one hundred and eighty-three acres, a total of three hundred and eight-three acres. He gives considerable attention to the raising and feeding of stock, and usually fatten two car loads for market annually. On coming to this country he was without means, but he has always made the most of his opportunities, and is to-day one of the well-to-do men of his community, owning two large and valuable farms under a high state of cultivation. Mr. Hansen's first wife died in 1892, leaving eleven children, four sons and seven daughters, as follows: Anna, wife of Henri Atsen; Hans Hansen; Peter Hansen: Mary, wife of Fredrick Kelding; Lena, wife of C. C. Sackett: Johanna, wife of Theodore Trulsen; Katie, wife of James McNall; Emma, wife of Jens Geronsen; Vina, now Mrs. Daniel Shippy; Johanis Hansen; Jacob Hansen.
