In the middle of the nineteenth century, New York City’s First and Fourth Wards were heavily identified with immigrants from Kerry, a county on Ireland’s southwestern seaboard.  However, a sample of Emigrant Savings Bank account holders for the Eighteenth Ward revealed a micro-colony of Kerry men and women living on the east side of Manhattan in the Gas House District. They illustrate how, even within Irish counties, there can be variations that link specific places of origin with specific areas of urban settlement.
