It depends on what year you are looking for and if you are positive that they entered through New York.
Castle Garden located on Battery Park was used as a point of entry to New York before the inception of Ellis Island in the 1890s. So if you are seeking a record for someone who emigrated to the United States through New York prior to 1890, you should check this website:

Ellis Island has many wonderful stories, is quite nostalgic, and many people like to think that their family members were processed through that facility.
Keep in mind that many immigrants didn't come through New York at all, as Philadelphia, Boston, Galveston, San Francisco, New Orleans and even ports in Canada were less expensive options.
It's much better to search for ancestors using broad terms (select several ports or leave it blank altogether) when looking for Immigration/emigration data.
You will probably be surprised at what you find. Good luck with your search.
