Nazareth's first wife was Ginney Brouwer (they were first cousins) and they had seven children. His second wife was Catharine Halley, a widow. No children by the second marriage. Nazareth married third, Deborah Wiltsie, a daughter of John Wiltsie and Jane Luckey. Nazareth and Deborah had eight children, giving Nazareth a total of fifteen known children. A family group sheet for Nazareth Brouwer and his three wives is available online.
Among the children of Nazareth Brouwer is Col. Henry Brewer (1804-1880). Henry was married to Rebecca DuBois and lived at Enfield in Tompkins County, New York. A chart of his descendants is online. Among this couple's three children is William Henry Brewer (1828-1910) a graduate of Yale College and an accomplished scientist and naturalist of the late nineteenth century. He was a professor of natural science at Washington College in Pennsylvania in 1858, and after the death of his first wife and their only child, he agreed to work on the first geological survey of the State of California. A preview of the journal of William H. Brewer, Up and Down California in 1860-1864 (University of California Press, 2003) can be found at Google books. Mount Brewer, a 13,576 foot peak in California's Sierra Nevada was named for William Henry Brewer.
Barbara (Johnson) Smith, a descendant of Col. Henry Brewer and Nazareth Brouwer, has aided me in compiling the descendants of Col. Henry Brewer.
