I had always been told that “absolutely everyone” on my mother’s side of the family is from Sézanne (Marne département (51)). Or so I thought, until…
One morning, last April, I felt compelled to resume my research on a side of my mother’s family that I hadn’t researched for a few years. I started with Pierre Gille François Girault (1777-1861) and his wife Marie Jeanne Breton (1778-?1856). They were the grandparents of my great-great-great-grandfather, Alphonse Girault, who was born in their house, in Sézanne, in 1831. At the time, the only information I had about them was their name, listed on Alphonse’s birth record.
Using the Archives of the Marne département (census records (recensements de la population), ten-year indexes“ (tables décennales)), Geneanet searches, and Google, I ended up finding their marriage record. I was stunned… They were married on 5 Thermidor year XII (July 24, 1804) in… Vert-Saint-Denis (Seine-et-Marne (77)), the village where I grew up!! (Not to be confused with “Saint-Denis” (Seine-Saint-Denis, 93), where you can admire the magnificent Basilica of Saint-Denis, necropolis containing the tombs of the kings of France).


Note: The website of the Archives of Seine-et-Marne is one of my least favorite archives websites… The website itself is great, fast, very nice. It’s when you get to the archives section that things get really annoying. So sloooooooow…. Be patient if your ancestors lived in that department! If you get a blank page, refresh your browser. Still a blank page after a few seconds? Refresh again! You finally get a page. Hurray! If you zoom in or out: you’ll stare at the “loading” wheel…! The best is to research their archives when everyone in France is having dinner or sleeping (all those French genealogists are slowing the site down… how dare they!), so check the time difference based on where you live. 🙂 (I live in Arizona. We have 8 hours time difference with France in the winter, 9 hours in the summer. I research “Seine-et-Marne” after 11am Phoenix time).
Second annoying thing: just like the Archives of Paris, they do not offer a “permalink” option. This means that if you click on the link I included below, it will take you to the first page of the register. To go to page 54, you will need to either type the view number (54), or use the arrows to navigate to page 54 (see bottom right of my images).

Marie Jeanne’s baptism record
Their marriage record mentioned that Marie Jeanne had been born on September 30, 1778 in Vert-Saint-Denis!! Back to the Seine-et-Marne Archives!
Oh the joy of finding any old record!

The marriage record had said that Marie Jeanne was “born on September 30”. However, her baptism record clearly states that she was baptized on September 30, but “born the day before”. Here is the transcription of her baptism record (in old French):
L’an mil sept cent soixante dix huit le trente septembre à êté baptisée par moy curé soussigné Marie Jeanne née le jour précédent en légitime mariage de Leonard Breton laboureur en cette paroisse et de Edmée Tircuit. Le parrain à été Antoine Guitard, la marraine Jeanne Botte qui ont tous deux de …. ….. déclaré ne savoir signer.
Pinsonnat, curé de Vert-Saint-Denis
In the year one thousand seven hundred and seventy-eight, on the thirtieth day of September, I, undersigned parish priest, baptized Marie Jeanne, born the day before from the legitimate marriage of Leonard Breton, farmer in this parish, et Edmée Tircuit. The godfather was Antoine Guitard, the godmother Jeanne Botte who both … declared not knowing how to sign.
Pinsonnat, priest of Vert-Saint-Denis
Since then, I have discovered more ancestors who were born, got married, died, and/or are buried in Vert-Saint-Denis, Pouilly-le-Fort, Cesson, Savigny-le-Temple, Melun, all villages or cities that I know very well. So my parents lived in Vert-Saint-Denis for almost 50 years, not knowing that 200 years before they bought our house, my mother’s ancestors had lived there. Oh the joys of discoveries thanks to genealogy!!
Pierre Gille François and Marie Jeanne lived in these cities




- Vert-Saint-Denis: Seine-et-Marne (77) – 91 km/56.5 miles from Sézanne and Chichey.
- Sézanne: Marne (51) – Only 5 km/3.1 miles from Chichey.
- Chichey, Marne (51)
- Paris (75) – 112 km/69.5 miles from Sézanne.
Pierre Gille François Girault and Marie Jeanne Breton moved a few times during their life. They were both born in Seine-et-Marne (Pierre Gille François was born in Liverdy-en-Brie, about 5 hours by foot from Vert-Saint-Denis). So far, I have found 7 children for them, but they might have had more children. Their first child, Adèle Sophie Girault, is Alphonse’s mother (my direct ancestors). She too was born in Vert-Saint-Denis, in 1805!
They had two daughters in Vert-Saint-Denis, then, by 1809 (birth of another child), they were living in Sézanne. Next, I found them living in Chichey in 1836. They seemed to have lived in Chichey until about 1846. At that date, I found them again on the census living in Sézanne, where they lived until at least 1851.
At that point, I had lost track of them, until I found the death record of Pierre Gille François (by then, he went by “Gilles”). He died in 1861, in Paris (5th arrondissement), where he was living with his daughter Mélanie and his son-in-law. His death record indicates “widower of Marie Jeanne Breton”).
I found a Marie Jeanne Breton death record in the “reconstructed archives” of Paris (I have more information about the Destruction of the Archives of Paris here). Those records contain very limited information, but I am pretty sure she is “my” Marie Jeanne, in the same 5th arrondissement of Paris as Pierre Gille François.
My guess is that they both moved to Paris to live with their daughter and son-in-law once they reached a certain age, in any case after 1851, date of the last census in which I found them in Sézanne. Unfortunately, census records for Paris before 1926 are only available “en salle de lecture” (you have to physically go to the Archives of Paris).
On a side note: their son-in-law was renowned Antoine Oleszczyński, Polish graphic artist and copperplate engraver.
The troubled times they lived in

Pierre Gille François and Marie Jeanne certainly lived during very troubled times when so many changes happened in France. One of them has an impact when we do our genealogic research: the French Revolution, which brought the infamous Republican calendar: a little tricky when you are researching the archives. But no worries: help is on the way! Go to my “Glossary” page and check the “Republican calendar” section for dates and months conversions.
