Irish immigrants were the largest immigrant group in Philadelphia’s prison population

Evidence

The largest single immigrant group in the City was the Irish. Of 520 male prisoners on January 1, 1826, 49 were Irish born. The Irish were also generously represented among the insurgents: Irish surnames appear frequently in the Minutes in connection with various incidents of rebellion in the prison. — Noel Ignatiev, How the Irish Became White, 164
