Casper Adler, from a "little German home across the sea," came in 1854. He was born in the village of Baldern, county of Narascheim, kingdom of Wurtemburg, Germany, in 1834. When nineteen years of age, he came to the United States. He was first employed in a brick yard at Milwaukee, and afterward on the Illinois Central Railroad, and spent a year at work in a brick yard at Galena, IL. In 1854, he came to Whitestown and entered forty acres of land on section 34, which he has since increased to sixty acres. He was married in 1863 to Catharine E. Miller, and six children were born to this union: Rudolph, Joseph, Andrew, Charles, Mary, and Caroline. Mrs. Adler departed this life in 1879, and Mr. Adler was again married in 1883 to Mrs. Edith M. Seaman.
I checked, and there is no patent online for the land described above, so Casper must have purchased instead of patenting the land. I was trying to determine whether he migrated from Germany in 1854 or to Whitestown in 1854, but you will probably need to check the censuses to find that. The wives of Casper are not further identified.
