GATES, HOLSEY (HALSEY) (1799-2 Nov. 1865) was an early settler of the WESTERN RESERVE and the namesake for the village of GATES MILLS in Mayfield Twp. Born in East Haddam, CT, to Nathaniel and Hannah Gates, the family moved to Delhi, NY in 1815 following Nathaniel’s death. Soonafter, Gates’ brother and sister (Jeremiah Gates and Clarissa Gates Brainerd) moved to northeastern Ohio, with Jeremiah eventually settling in the village of BROOKLYN and opening a sawmill with the assistance of brother Nathaniel, who permanently settled there ca. 1824.
