We began with a dataset drawn from the records of the Emigrant Industrial Savings Bank, held by the New York Public Library and digitized by Ancestry.com. This consisted of 194 people with an address on Mott Street, between Chatham Square and Grand Street (i.e. Nos. 1-151 Mott) who were associated with 257 distinct accounts, some jointly held.
There were 188 people who reported their place of birth; the ethnic distribution, while predominantly Irish, reflects contemporary emigration from Germany, Poland and Prussia too:
By far, Sligo natives outnumbered EISB Mott Street account holders from any other county in Ireland, reminding us of the long-standing pre-Famine links between this part of Ireland and New York represented by the Nealis family. The most well-known exodus from Sligo was underwritten by Lord Palmerston in the middle of the century, primarily from his estate along the coast north of Sligo town. Honora O’Neil’s emigration from Ahamlish in 1834 (the date may have been off by a few years as she was recalling it more than twenty years later for the EISB accountant) may indicate that she was among the first of Palmerston’s tenants to opt for emigration when he undertook ‘squaring’ – a transformation of the historic farm holdings in the area. Among those who strenuously protested such modernization efforts was a member of the Feeny family; it is perhaps not uncoincidental that Patrick, Owen and Elizabeth Feeny as well as their widowed sister Bridget Feeny Curry emigrated to New York, settled next door to each other at Nos. 100 and 103 Mott Street and opening savings bank accounts. Their arrival between 1847 and 1851 does not make them Famine refugees per se since Palmerston’s “programme of emigration” acted as “a safety valve;” their inducement, however, was most likely the threat of eviction so it was not necessarily voluntary. 
The emigrants from Co. Louth in this dataset are almost entirely part of the extended Pentony family from Stabannon, although the name is historically associated with the Drybridge and Tullyallen area.

Palmerston also owned townlands in Drumcliff, the next parish to Ahamlish, as well as in Sligo town and in townlands to its south around Ballymote.
