Abstract: Family papers of Elizabeth Comstock, a physician at Arcadia, Wisconsin. Although the collection contains a few items on medical topics, the bulk of the papers consists of correspondence, diaries, business records, scrapbooks, and genealogical notes by and about her forebears in the Comstock and Durrin families. The major portion of the papers relates to her uncle, Cyrus Ballou Comstock (1831-1910), a prominent army engineer. Also in the collection are papers of Dr. Comstock's father, Noah D. Comstock (1832-1890), who emigrated from New York State before the Civil War, went to California in 1858, then returned east to settle in Arcadia. Other portions of the collection include Civil War letters from Walter Comstock, a lieutenant in Company A, 25th U.S. Infantry, at the time of his death; and letters written by Elizabeth Comstock's brother Adam (1871-1898) while a student at the University of Wisconsin and at Gottingen University in Germany. Two record books of the S.T. and F.A. Robertson General Store at Humbird, Wisconsin, are also present.
