A Thousand Years of Two Italian Families: The "de Judicibus" and "Giliberti" Digital Genealogical Archive

This paper describes a large-scale digital genealogical archive documenting two Italian family lineages — de Judicibus and Giliberti — across a span of approximately one thousand years, from the tenth to the twenty-first century. The archive, accessible as a website developed entirely by the author, as of June 2026, contains records of about 4,100 individuals distributed across Italy and fifteen other countries, drawn from primary sources including Latin notarial acts, diocesan registers, cadastral archives, heraldic documents, and personal manuscripts. The paper discusses the structure of the resource, the methodological criteria adopted for source evaluation and genealogical attribution, the technical architecture of the platform, and the research questions the archive makes tractable. The resource is offered as a freely accessible reference tool for historians, genealogists, and researchers working on medieval and early modern Italian social history on https://genealogia.dejudicibus.it.
