TNG is a fully functioning family tree application that can house your family trees, branches, ancestors, their families, cemeteries and stories. Even more, it can handle your sources, references and repositories. Further, TNG holds onto photos, headstones, military records, census, birth / marriage /death / burial documents, and even more.
And most importantly, it does it all while being a software application on the internet. TNG is a web-based family tree application that resides on your website.
