In the early 1800's port cities in the USA bore the burden of immigration. By the time they arrived, so many immigrants were tired, hungry and poor they ended up in the City Almshouse.
As far back as the colonial era, New York City assumed responsibility for its citizens who were destitute, sick, homeless, or otherwise unable to care for themselves. The city maintained an almshouse, various hospitals, and a workhouse on Blackwell's Island (now called Roosevelt Island) for the poor.
Part of the information taken Almshouse clerks was the place of birth of each person, the name of the ship they arrived on and where the ship sailed from. Using this online (free) database will allow you to find individuals from many countries and many states within USA.
I have just uploaded new records for NY City Almshouse for 1826 and 1827. This adds to the existing records on Olive Tree Genealogy for 1819, 1820, 1821, 1822, 1823, 1824, 1855,1856,1857 and 1858. When this project is finished the records will be complete from 1819-1844 and 1855-1858
