Genealogical research encompasses a practice and method that has been of great importance over the centuries, not only because family origins had a strong symbolic function, but also because it helped legitimize individual and family claims or resolve legal problems. The practices and methodologies of this work have changed significantly in recent decades, especially with the introduction of the digitization of public archives and their access through the Internet, democratizing genealogy, once a pursuit only of the elites. This workshop aims to address the theme of ascending genealogy, presenting the methodologies and resources necessary for constructing a genealogical tree.
