Project Scroll Research Note 2026-30: Deadwood Lake: Diamond Lake, Cass County, Michigan, under an older name in Blois's Gazetteer of 1838

John T. Blois's Gazetteer of the State of Michigan (Detroit, 1838) names no Diamond Lake in Cass County. Its county entry lists the lakes as "Pleasant lake, Stone lake, Deadwood lake." It places Geneva, "a small settlement situated on the north side of Deadwood Lake," "2½ miles east of Cassopolis," and Young's Prairie, "in Penn township, Cass county, on the north-east of Deadwood lake." The county history of 1882 says that Geneva, the first county seat, was "laid out on the north bank of Diamond lake," and Glover (1906) that its plat of 1832 "shows that the village was laid out on the north side of Diamond lake." Young's Prairie lies north-east of Diamond Lake. By this reading Diamond Lake was still called Deadwood Lake in the late 1830s. Project Scroll Research Note 2026-30, version 1.
