STATUS UPDATE: After review of the Pilot Genealogy (below), implementation (and matching/merging) in progress

Updated: June 20, 2011

Objective

An attempt to bring clarity to the dynasty of the Counts van Loon / de Looz. In Geni - as well as throughout all online sources - there is significant confusion (see a list of related names and possible connections here: Names of counts de Looz/van Loon). This confusion starts with the fact that, at heart, this is a Dutch/Flemish dynasty under the name 'van Loon', but throughout aristocratic tradition the alternative French name 'de Looz' has persisted.

Many lineages may be concerned by this project:

• Counts of Metz
• Counts of Mainz
• Counts of Rieneck
• Counts of Duras
• Dukes of Brabant
• Lords of Mechelen and Grimbergen
• Counts of Luxembourg
• Counts of Bliesgau / Blieskastel...

Within this project, we should achieve maximum certainty about who was married to whom, and which children belong to which parents.

There are various old scholastic sources online. Some of them hold elements of 'the truth', but other elements have been proven to rely on errors of interpretation or old falisified documents.

Beware, knowledge of various languages such as German, Dutch, French or Latin is no luxury in this project. We're talking about events between abt. 950-1364, so this is a challenge!
