"The Vinegar Hill Historic District... a residential remnant of the early nineteenth-century neighborhood that occupied the blocks between the Brooklyn Bridge and the Brooklyn Navy Yard. By the late nineteenth century, the large number of Irish residents had given the neighborhood the popular name "Irishtown," although other ethnic groups also lived in the area [Germans, Norwegians, Swedes, Poles, Italians, and Eastern European Jews]. ... The groups of houses that survive within the Vinegar Hill Historic District retain their historic architectural character and create a distinct sense of place, recalling a significant era in Brooklyn's history.

Area lots " were developed individually or in small groups in the 1840s and 1850s with houses that have Greek Revival and Italianate characteristics. Further residential construction occurred on a few remaining vacant lots on Hudson Avenue, Water Street, and Front Street in the years following the Civil War. By the late nineteenth century, the Vinegar Hill area had become a dense residential and industrial neighborhood. Hudson Avenue was a busy commercial strip, as evidenced by surviving ground-story shopfronts. .... Most of the residents worked on the waterfront, in the Navy Yard, or in neighborhood industries. By 1903, major changes began to occur in the area as a result of the building of the Manhattan Bridge and industrial expansion in the decade following the consolidation of the City of New York in 1898. Hundreds of small dwellings were replaced with large industrial buildings. More houses were razed in the 1920s and 1930s for truck storage facilities, parking lots, and warehouses, a pattern which continued after World War II.

It looks like 23 Park Row is just across the street from the area usually shown as the notorious Five Points area. It is just a couple of blocks from City Hall, then identified as Tammany Hall on the 1831 map.

A disease-ridden slum with.high population density, disease, infant and child mortality, unemployment, prostitution, violent crime. . However, it could be considered the original American melting pot, at first consisting primarily of newly emancipated blacks (gradual emancipation led to the end of slavery in New York on July 4, 1827) and Irish, who had a small minority presence in the area since the 1600s.[9] The local politics of "the Old Sixth ward" (The Points' primary municipal voting district),

...Five Points is alleged to have sustained the highest murder rate of any slum in the world. According to an old New York urban legend, the Old Brewery, an overcrowded tenement on Cross Street housing 1,000 poor, is said to have had a murder a night for 15 years, until its demolition in 1852.[13][14]

• I think Margaret was born New York despite the conflicting entries.
• With the Civil War documentation, I'm confident John was born in Ireland. It's quite possible it was advisable to obscure the Irish heritage in the earlier census years.
• The information on Maggie's mother may be another story. Disparate data may support the notion that there was a second marriage -- that her birth mother was Irish and her step mother was vorn in NY or CT.

Is wife Sarah a Bunnell? Is she the first wife.

The Bunnell name is found early in Connecticut history- in Litchfield County, in the New Haven area and in the Fairfield Westport area.

There is a Bunnell associated with the building of ?Southport Congregational Church.  "Significance: The Southport Congregational Church is designed in the High Victorian Gothic manner by locally prominent architects Lambert and Bunnell, and erected in 1874-75."  https://www.loc.gov/item/ct0034/

Henry A. Lambert and Rufus W. Bunnell were a Bridgeport architectural firm who designed buildings in Southport during the 1860s and 70s.

There are several Bunnell families in Westport.
