ALBERT COOK.
Prominent among the substantial farmers of Sharon township whose success in life is due to their own industry, perseverance and good management is Albert Cook, who was born December 20, 1859, on the farm where he now resides. He is a son of Marshall and Magdalina (Housell) Cook, who were natives of Germany, and emigrated to the United States in 1852. They spent two years in Lancaster county, Pennsylvania, where the father worked at the mason's trade, and then came to Clinton county, Iowa, where he entered the land now owned and occupied by our subject.
