Goals of Mini-Project

There are a couple goals that this project seeks to fulfill:

  • Cleanup of existing profiles: This includes merging away duplicates (there are many), changing LNABs as needed, and adding sources.
  • Adding additional ancestors: Catherine de Baillon has a very interesting pedigree. While there are many ancestors that can be added, there are a couple parts of her lineage that are of particular note:
    • Lineage to Jean Lhullier (200) and Jeanne de Vitry (201): While not royalty, these ancestors are the common ancestors of many royals. Living examples include Queen Elizabeth II and Felipe VI of Spain. The direct ascendance of these royals also needs to be worked on, which would likely be in close collaboration with the Euro Aristo project. Currently, the relevant royal lineages back to Lhullier and Vitry dead-end on WikiTree at Marie Sybille de Nassau-Saarbrücken and Christina Salm, respectively.
    • Lineage to Eudoxia Lascaris (7745): Eudoxia's pedigree is a very interesting one. Her father's side presents Catherine Baillon's quickest known path to royalty, in this case to the Byzantine Emperor Theodore II Doukas (Lascaris). Her mother's side also provides additional paths back to Charlemagne.

Note about Tables Below

The tables below are based in large part on the following work:

René Jetté, John P. Dulong, Roland-Yves Gagné, Gail F. Moreau, and Joseph A. Dubé. Table d'ascendance de Catherine Baillon: 12 générations. Montréal, Québec: Société généalogique canadienne-française, 2001.

Helpful Online Links

  • This website has been administered by the same team whose research was published in the Table d'ascendance.
  • The team cited above generously agreed to have the American Canadian Genealogical Society publicly host a previously published article that provides evidence of the direct lineage back to King Philippe II Auguste. A more recent article casts doubt on the specific lineage from the aforementioned to Charlemagne, but that need not concern us as other routes to Charlemagne from Philippe II are readily available. The article is free to read or download and is written in English.

Yes, there is more evidence provided by Jetté. I've been meaning to work on the Lombard family for some time-I'll document it soon, probably in the next week or so.

I've added a couple of references for Jean Lombart and Doulce Vienne. Unfortunately, while they provide a lot of biographical information on Jean Lombart, the evidence linking Catherine Lombart to these parents is still difficult to explain. Does Jetté have more on Catherine's parents?

I've updated the progress as of February 4, 2018. It's cleaned up to Generation IV and almost all of Generation V.

From footnote 33 on page 53 of Jetté 2001: La preuve du père et de la mère de Gabriel se trouve dans l'inventaire après décès de son père, en date du 2 juin 1545 : « inventaire après décès de Nicole Le Sueur, conseiller du roi au parlement, dressé à la requête de Jeanne Guillard, sa veuve, tutrice de Louise et Agnès Le Sueur, ses filles, et à celle de Thierry Dumont, seigneur d'Arcy-en-Multien, tuteur de Gabriel et Thibault Le Sueur, enfants du défunt et de Marie Raoland, sa première femme »

Hi, I've been trying to do work for Gabriel Le Sueur . Do we know for sure perhaps through Jette, 2001 that his father is Nicolas? I can't find anything confirming this connection, only that Guillaume was has father and Nicolas was his brother.

Waast de Marle is an aristo, and the convention then is to eliminate the "de" from LNAB and the older the profile is the more it should be enforced - see Name Fields for European Aristocrats - it took me a while to get used to, but could not do it another way now.

I believe that the merge direction for Waast de Marle should be Marle-10 into De_Marle-7-would be good to hear if others agree.

I'm in the process of updating the tables. A lot of work has been done with sources and merges. All the profiles up to Catherine's great-grandparents are now clean.
