The family of Valentine Compagnon

There is not a documented “Compagnon family of Paris” in the sense of a single, well‑traced lineage; you can, however, build a Genealogy 101–style sketch around the surnames Compagnon and Delafosse, and then try to place Valentine in that broader context.

What we can say about Valentine

• Valentine Delafosse Compagnon was an actress in France and lifelong partner (sometimes described as wife or mistress) of the photographer Eugène Atget.
• They met in the 1880s, in theatrical circles, and remained together in Paris until her death in 1926, one year before Atget’s own death.
• Published biographical sketches of Atget focus almost entirely on him and give almost no genealogical detail about Valentine—no parents, exact birthplace, or extended family.

In other words, in the mainstream literature Valentine appears more as a biographical note in Atget’s life than as a member of a documented “Compagnon family” with a worked‑out pedigree.

The surname “Compagnon”

• The surname Compagnon is French, from Old French compaignon, “companion, partner,” originally “bread‑fellow” (one who shares bread).
• Commercial surname compendia also connect it etymologically to Italian forms like Compagni and Compagno, sometimes tracing early noble branches in Padua, but those claims are generic surname history rather than proof of a specific Parisian line tied to Valentine.
• Variant forms you may see in records include Compagnon, Le Compagnon, Compagnonne, Compagno, Compagni, etc.; some databases treat “Le Compagnon” as a separate surname.

For a Paris‑focused project, that means you would look first for Compagnon (with or without “Le”) in Paris and surrounding départements, and only treat Italian connections as a hypothesis if you actually see an immigrant ancestor in the records.

The surname “Delafosse”

• Delafosse is a French toponymic or habitational name, literally “from the ditch/pit,” from la fosse with the preposition de fused.
• Onomastic sources treat it as a variant of Lafosse; you will often see people indexed under Delafosse, De Lafosse, Lafosse, and even De la Fosse, depending on the clerk and period.
• There are several distinct Delafosse/De la Fosse families in France; one well‑documented cluster appears in central France (Cher, Berry region), but again that is a surname‑level pattern rather than a proven tie to Valentine.

The compound “Delafosse Compagnon” in her name may reflect:

• A double surname (Delafosse as a family name plus Compagnon as either another family name or a stage name), or
• A birth surname plus a married name, or
• A stage name constructed to sound distinguished or memorable.

Without a birth or marriage record, you cannot assume a particular structure.

How to research the “Compagnon family of Paris”

For a Genealogy 101–level plan, you would proceed like this:

1. Anchor Valentine in the civil records.
   • Target: locate her civil death record in Paris (1926), which should list at least age, usual residence, and often birth place and parents’ names.
   • Use the Paris civil registration and decennial indexes (état civil / tables décennales) via the Archives de Paris site; search under Compagnon, Delafosse, and Delafosse‑Compagnon.
2. Reconstruct her birth identity.
   • Once you have an age or exact date/place of birth from the death record, look up the corresponding birth registration to see her full legal name and her parents’ names and occupations.
   • Pay attention to whether Delafosse and Compagnon appear as two family names, one being a middle name, or one being added later (e.g., mention of a prior marriage).
3. Build out the Compagnon line in Paris.
   • With parents identified, search earlier Paris (or provincial) records for their marriage, births, and deaths, working backward one generation at a time.
   • Check census‑like sources, military conscription lists for any male Compagnon relatives, and notarial records (marriage contracts, successions) which often mention extended kin in Paris‑area families.
4. Map surname clusters, not “one big family.”
   • Use online databases (e.g., FamilySearch, Geneanet, MyHeritage) to see where Compagnon and Delafosse appear in 19th‑century France, especially around Paris.
   • Treat each Compagnon household you find as a separate hypothesis until a document explicitly connects it (through parents, witnesses, or shared villages) to Valentine’s known people.
5. Distinguish theatrical/stage identity from legal identity.
   • Because Valentine was an actress, trade papers, cast lists, and theatrical directories may use a stage name that does not exactly match the civil‑record name.
   • If you find a Valentine Compagnon or Valentine Delafosse in civil records but not the compound form, look for corroborating details (birth date, spouse Atget, address) before merging identities.

What a “Genealogy 101” narrative might look like

Once you have done that basic research, a family overview for the “Compagnon family of Paris” tied to Valentine could be structured like this (template, since the actual details have not been published):

• Explain the meaning and geographic spread of the surname Compagnon and the related forms (brief paragraph on etymology and distribution).
• Introduce the earliest known Paris‑area Compagnon ancestor you can document (e.g., “Jean Compagnon, a cabinetmaker in the 18th arrondissement, born in X, married to Y”), with a sentence or two on occupation and neighborhood drawn from civil and notarial records.
• Describe how the family moved within Paris (or migrated in from another region), noting addresses and occupations that show their social milieu (artisans, clerks, actors, etc.).
• Place Valentine in that tree, identifying her as a daughter or granddaughter of the identified Compagnon couple, and summarizing her path into the theatre and her lifelong partnership with photographer Eugène Atget.
• Close with a short note on open questions (e.g., uncertainty about any Italian connection suggested by generic surname sources, absence so far of noble or Huguenot ties, etc.).

Right now, the published sources stop well short of that; they give us Valentine’s profession, relationship, and approximate dates, but not a worked‑out family. To turn your curiosity into a proper “Genealogy 101” for this family, the pivotal next step is to pull her Paris civil records and then work outward generation by generation from there.
