Family Tree Registry - Genealogy Respecting Privacy

The Family Tree Registry is a free resource facilitating the exchange of genealogical information while maintaining the privacy of its users and their family trees. The Registry does not contain family trees. Instead, it functions as a central repository of descriptive information about family trees (including where to find them) and surnames appearing on them (but not about individuals). It also functions as a search engine, enabling users to find family trees by specifying properties the trees or surnames on the trees must possess. Properties such as ethnicity/sub-ethnicity, religion/sub-religion, place, date last modified, whether surnames or family trees contain nobility, whether they contain rabbis, whether they have associated DNA (genetic) information, and more are searchable. Surnames and places can also be specified and searched according to their native spelling in non-Latin characters (Chinese, Hebrew, Polish, etc.). When logged in, searches you perform can be saved so that you can easily retry them in the future, without having to respecify the search parameters. The Family Tree Registry is not limited in scope to family trees that are available online. You can also register family trees that are privately maintained offline, that are published in books, or that can be found in repositories.
