Entries are assembled from contemporaneous press reporting, judicial and parliamentary records, church and municipal registers, published histories, photographic material, and recorded testimony. Each claim is traced to the earliest source available to us, and later retellings are treated as secondary.
An entry is published once at least two independent sources agree on the date, the place, and the essential facts, or once a single primary document — a registry, a court file, a first-person account — can be cited directly. Where only one source exists, the entry says so plainly.
The archive corrects itself in public. When new material changes a date, a figure, or an attribution, the entry is amended and the change is acknowledged rather than quietly overwritten. Researchers, families, and witnesses are invited to submit documents, photographs, or corrections.
