Eighty-five men, all natives of Ireland, were admitted to Sing Sing in 1870.

- 72% of Irish prisoners were committed by two judges: Gunning S. Bedford and John K. Hackett.
- 76% of Irish prisoners had been in the USA twenty years or less; the majority had emigrated after the Famine, i.e. 1852 or later.
- 59% of Irish prisoners had emigrated as children aged 10 or under; the majority of those (27 of 40 or 67.5%) were aged 5 and under.

- Only 5% of Irish prisoners were considered intemperate, i.e. problem drinkers.
Eighty-six percent of Irish-born prisoners in Sing Sing in 1870 were Catholics. Although the majority of the New York Irish at that time were also Catholic, there may have been bias in the arrest and sentencing of Irish Catholics since anti-immigrant nativism and prejudice were common. This makes the twelve Irish Protestant prisoners an interesting case study, especially since their surnames cannot predict religious affiliation.
Ten out of the twelve Protestant prisoners gave an address in Manhattan when they were admitted to Sing Sing. However, when looking at the exact addresses and locations of where the prisoners lived when they were arrested, there is no pattern that makes these arrests significant to each other. This suggests that Irish Protestants were integrated with Irish Catholic populations, as in the first, fourth, and seventh wards along the East River waterfront or in the sixteenth and twentieth on the west side above 14th Street.
The range of crimes committed by the Irish was the same, regardless of being Protestant, for example,
- Richard Folks was a 38-year-old carman who had emigrated from Ireland in 1852 and lived on Cherry Street in the 7th Ward. He was convicted of stealing two barrels of whiskey in Manhattan and selling them in Williamsburg. He was sentenced to Sing Sing for only one year because he had “shown a previous good character,” according to the New York Herald, 13 July 1870, p. 5.
- The bookkeeper James Martin, age 34, confessed to 3rd degree forgery and was sentenced to three years in Sing Sing. He was one of the eight Irish Protestants with that term in the prison in 1870 and he was also one of the nine Irish Protestants who were married. The clerk David H. Smyth, also married, got five years for grand larceny.
- Both James McDowell and Thomas O’Brien worked with horses. Both were convicted of assault with a deadly weapon and were sentenced to five years in the State Prison.
- The New York Tribune, 26 October 1870, reported that John Robinson was “found guilty of a most offensive crime, and was sentenced to the State Prison for ten years.” His entry in the Sing Sing Admission ledger is more explicit: sodomy. Three Catholic Irish inmates were convicted of rape or attempted rape.
Of the 85 Irish-born prisoners in Sing Sing in 1870, sixty-five were moderate drinkers, making up 76% of the selection, while fourteen (16%) were temperate, and four (5%) were intemperate. Two prisoners did not report their alcohol use, or it was not recorded.
Based on the four inmates who were categorized as ‘intemperate’ in this sample, there is little to no correlation between intemperance and crime, despite common thought at the time that intemperance was a cause of crime. All four committed either burglary or larceny, neither of which were considered violent crimes. In contrast, the Irish prisoners convicted of violent crimes were either temperate or moderate drinkers. Since Grand Larceny was the most common reason Irish men were committed to Sing Sing, inmates of all degrees of temperance are represented in this subset: 2 out of the 4 intemperate prisoners committed this crime, 17 moderate drinkers out of 65 were locked up for it, and 6 of the 14 temperate men were admitted for it as well.
Three out of the four men in Sing Sing who were classified as intemperate were Catholic and one was Protestant, showing that religious belief did not always equate with teetotalism.
While many Irish in New York in the middle of the nineteenth century found success in different walks of life, others fell into the trap of crime. A third of the 85 Irish-born inmates in Sing Sing prison in Westchester County in 1870 had been convicted of larceny, which is defined as the unlawful theft of someone’s property without the use of force. According to 2018 Federal Bureau of Prisons statistics, only 4.7% of inmates are serving sentences for Burglary, Larceny, or Property Offenses, indicating a significant shift in reasons for incarceration since the 1870s.
Out of the eighty-five prisoners used as a sample, sixty-four were able to read and write, three could only read, and sixteen were completely illiterate. Being illiterate put some of these men at an even greater disadvantage on top of being an immigrant to New York City and a minority. Of the 19% of Irish-born inmates who were illiterate, nearly half of them were laborers.
Although the most common occupation among the prisoners was clearly laborer, 72% of the laborers had been born in the decade of the 1840s, indicating the extent to which New York City’s unskilled workforce depended on strong young men. The Twenty-third Annual Report of the Inspectors of State Prisons of the State of New York (1871) confirms that most prisoners were laborers who committed crimes against property as opposed to against a person, and that the majority were first-time convicts and between the ages of 19 and 28.
The second most common job held prior to conviction was in the building trades. Five construction workers committed grand larceny and three committed robbery. Overall, it can be concluded that poor people, or more appropriately, people with low-paying jobs, were committing crimes of opportunity driven by economic necessity during the 1870s. Cain Mansfield, for example, stole $80 from Agnes Ledfelt, a woman who lived in his building on Vandewater Street; he was a 35 year old plasterer with a wife in San Francisco. He confessed to attempted grand larceny and was sent to Sing Sing for two years.
