August A. Kluck, Jr. One of the good farms of Sharon Township has received the care, cultivation, and diligent labor of the Kluck family for about half a century. This farm is owned by August A. Kluck, Jr., who grew up there, and has supplemented the diligence of his father in perfecting arrangements and equipment until he now has a place that affords the maximum of returns for the labor involved.

On this farm August A. Kluck, Jr., was born in December 1875. He is a son of August and Mary (Esker) Kluck, both natives of Poland. His father was born February 27, 1840, and the mother in 1848. The paternal grandparents, Andrew and Annie Kluck, immigrated to America and arrived in Canada July 24, 1861. In November of the same year they removed to Milwaukee, the grandmother following her husband in 1862. She died in Milwaukee in 1862, when about 60 years of age. Andrew Kluck then came to Portage County and died here about 1880, at age 84. Their children were John, Leonard, Vincent, Michael, August, Julia, and Paulina. The only two now living are August and Paulina. The son Michael died in Poland.

August Kluck, Sr., accompanied the family to America and about 3 years after locating at Milwaukee he enlisted and fought for the Union cause. His enlistment was on October 28, 1864, and he served until the close of the war. In 1865 he returned to Milwaukee, married the same year and took his bride to Portage County in the fall of 1865. His wife was a daughter of Peter and Agnes Esker, who located at Milwaukee in 1862 and in 1865 came to Portage County, buying a farm in Sharon Township. Both lived there until the end of their lives. The children in the Esker family were Nick, Mary, Annie, and Paulina. Paulina is now deceased.

August Kluck, Sr., on coming to Portage County bought 80 acres as the nucleus of the farm which has been above described. Later he acquired 120 acres and ten acres of his have since been sold, leaving the present place of 190 acres. Only 11 acres of the ground had been cleared with the senior Kluck acquired it, and he bought his family to live in a log house. The land for cultivation has since been widened over most of the farm, and the buildings are all first class. Mr. Kluck, Sr., is a democrat and he and his family are members of the Polish Catholic Church at Polonia. Fourteen children were born to him and his wife named: John, Nick Alexander, Frank, Anastasia, Helen, August, Mary, Annie, Joseph, Leo, Maggie, Martha, and Veronia. All are still living except John, the first child. August Kluck, Sr., in the early days served as side supervisor of the township and later for about 13 years was chairman and director of the school board.

August A. Kluck, Jr., grew up on the home farm and was educated in parochial schools. In 1903 he bought the old homestead from his father and now has the responsibility of looking after 190 acres devoted to general farming and stock raising. He is a democrat in politics and a member of the Polish Catholic Church at Polonia. In 1903 Mr. Kluck married Miss Josie Wanta. She is a native of Sharon Township, born in 1880, daughter of Joseph and Kate Wanta, who are still living on their home farm in Sharon Township. Mr. and Mrs. Kluck have a bright and interesting family of eight children: Frances, Georgiana, Richard, Alphonse, John, Margaret, Stancye, and Louise.
