As the cosmopolitan gateway to the United States, New York City has always been a magnet for immigrants. Throughout the United States an estimated 40 million can trace roots to an ancestor who lived in Brooklyn. While many families passed through or settled in Gotham, not all family members came to the US, and some of those who remained in Europe and elsewhere may have lost contact with their American cousins.
While on-site research is the optimal approach to research, this is not always convenient or feasible, especially now.
Nevertheless, much can be accomplished in advance or in lieu of physical travel. Components of New York City family history can be identified without setting foot on Broadway using a broad array of free and subscription internet sites as well as some conventional sources.
