When you drive past the stately columns at 1608 Genesee Street, you might mistake it for just another library. But inside the Oneida County History Center Utica, you will find the physical evidence of America’s wildest 19th-century crime syndicate and the remnants of a “free love” utopian cult that became a silverware giant.
The stately home of the Oneida County History Center on Genesee Street.
This isn’t just a place for dusty ledgers. It is the repository for the stories that made Central New York famous—and infamous. If you are visiting the Mohawk Valley in 2026, here is your guide to the Oneida County History Center Utica, from the Loomis Gang files to the Hall of Fame.
The Loomis Gang: America’s First Crime Family
Digging into the past: The center holds thousands of rare documents and maps.
Long before the Mafia ruled New York City, the Loomis Gang ruled the Nine Mile Swamp just south of Utica. The Oneida County History Center Utica holds critical archives documenting this family of horse thieves and arsonists who terrorized the region in the mid-1800s.
- The Story: Led by the matriarch “Wash” Loomis, the family stole horses, burned down courthouses to destroy evidence, and bribed judges. They were the “Sopranos” of the Civil War era.
- The Artifacts: Researchers often visit the center to dig through court records and maps that detail the gang’s reign of terror. It is a must-visit for true crime fans wanting to see the original locations on old maps.
The Paradox: Utopians and Bear Traps
Oneida County History Exhibits
One of the strangest collections at the Oneida County History Center Utica involves the Oneida Community. This was a religious utopian commune famous for “complex marriage” (sharing partners) and… manufacturing deadly game traps.
- The Newhouse Trap: The center’s collection includes examples of the “Newhouse” game traps. These steel traps, invented by commune member Sewell Newhouse, were the gold standard for fur trappers across North America.
- The Contrast: Seeing these brutal industrial tools alongside the history of a pacifist, communal society is a jarring but fascinating look at Utica’s industrial past.
Genealogy and “Sin City” Archives
For decades, Utica was known as “Sin City” due to its organized crime connections and political corruption in the mid-20th century. The Oneida County History Center Utica is a goldmine for anyone tracing their family roots through this turbulent era.
The library houses thousands of surname files, city directories, and maps. Whether you are looking for a Civil War ancestor or trying to find out if your great-grandfather ran a speakeasy during Prohibition, the archivists here can help you pull the specific file.
