William P. Trowbridge, USMA 1848

Born May 25, 1828,     died August 12, 1892

"The Cass Expedition to the Great Lakes: 1820.  Though regarded as an authority on the languages and customs of the northern Indian tribes, Michigan governor Lewis Cass declared himself "not competent to speculate upon the natural history of the country through which we may pass" and asked Secretary of War J.C. Calhoun to appoint to the expedition "some person acquainted with zoology, botany, and mineralogy." Accordingly, Calhoun appointed Henry Rowe Schoolcraft, Captain D. B. Douglass, Charles C. Trowbridge (1800-1883), and Dr. Alexander Wolcott."  [Quoting http://www.amphilsoc.org/library/guides/stanton/0335.htm ]

I suspect that Charles Christopher Trowbridge (1800-1883) was the father of William P. Trowbridge (1828-1892). Evidence for this is that C. C. Trowbridge was secretary of the Board of Trustees for the University of Michigan from 1821 to 1835. In addition the elder Trowbridge would have known Douglass well from the Cass Expedition.
