The genealogical numbering of the descendants of Jean Trudelle and Marguerite Thomas

The genealogy of the large family descending from Jean Trudelle and Marguerite Thomas has its own numbering system. Father Paul-Eugène explains the principles in the first pages of the 1950 genealogical dictionary.

Principles for classifying generations

According to this method, it is the parent generators who define each generation:

  • The 1st generation is made up solely of the ancestor Jean Trudel. His children make up the 2nd generation.
  • His grandchildren form the 3rd generation, and so on.
  • Each generation groups together the generators, that is, the parents, as well as their generated, that is, their children.

Role of the progressive marginal number

People who do not become generators in the genealogy only appear in the marginal progression. This is especially the case for singles, priests, monks, nuns, and married daughters. To find them easily, just know their parents’ names or check the index.

Case of Married Men

Married men appear twice in the system: first as sons in their father’s generation, and then again as fathers with their own children.

For example, Nicolas Trudel, husband of Thérèse Meunier, belongs to the 4th generation under number 23. He first appears as a son in the 3rd generation, at number 9, which is his father’s number. He then appears as a father, with his children, in the 4th generation, at number 23.

His sister Pélagie, wife of Pierre Ouvrard, appears only once: at number 24, on the side of the 4th generation, coming from the 3rd generation, number 9.

Tracing an ancestral line

For each number assigned to a generator, the names and numbers of its parents are listed. This setup makes it easy to quickly trace the full ancestral line of each Trudel.

The Branches

Our genealogical database contains more than 56,000 individuals. The couple Jean Trudelle and Marguerite Thomas had eleven children, eight boys (two of whom died in infancy) and three girls. Of these eleven children, only five sons had a direct paternal lineage that stretches to the present day. These sons are the branches of our genealogy.
