This will be a review of the Austrian nonprofit organization known at Matricula-Online (matricula is Latin for “register”). It is under the umbrella of the International Centre for Archival Research – US (ICARUS) and seeks to digitize church records. It has a major focus on the vital records kept by the Catholic Church. More than seven million pages of church records are online and growing. The databases include Catholic church records from the 1500s to the 1900s. Learn how to navigate Matricula-Online and see some examples of church records. Additionally, a brief review other European sources such as Archion and Geneanet will be made. A Zoom link can be found on the Kolping Cincinnati Genealogy website for this date.
