Hi Terry...... From History of Monroe County, MI. by Talcott E. Wing, 1890, under Milan Township:
Charles E.THROOP, was born at York, Washtenaw County, Michigan, April 10, 1860. His parents were eastern people, his father being born in Vermont and his mother in Albany, New York. They came to Michigan in 1860, settling upon a farm. Charles remained at home until 1886, when he purchased a grocer's stock and engaged in the grocery business. Previous to this he had worked as a stationary engraver. April 10th he married Mary Duboise, of Milan. She was born in LaSalle, Monroe Co., Michigan, July 14, 1870.
I hope this helps some...... Mike
