This post contains two parts. In the first part I present a novel-like view of the events in Montécheroux during the Napoleonic Era (1799-1802). The second part provides a detailed analysis of both the form and content of the records extracted from images of the original records.

Part I: The Chronicles of Montécheroux

The Measure of Iron and Blood (1799–1802)

The dawn that climbed over the ridge of the Lomont in the spring of 1802 did not bring the terror of the previous year. The terrible red sickness that had stolen thirty-two children during the blistering summer of Year IX had finally burned itself out against the cool limestone of the High Doubs. The small, freshly mounded graves in the communal churchyard were now carpeted in wild mountain clover, and once again the familiar song of Montécheroux filled the narrow valley: the steady rasp of watchmaker files, the thud of the wheelwright’s mallet, and the dull, rhythmic lowing of cattle turning up the black earth along the terraced pastures.

In the stone house of Jean Germain Voisard—the author’s fifth great-grandfather—the morning fire crackled cheerfully under the iron kettle. Jean Germain, now forty-eight, was a man carved from the very topography of the Jura: broad-shouldered from swinging the scythe, but possessing the sharp eye and delicate hands of a craftsman. Across the oak table sat his wife, Marie Angélique Lachat, the author’s fifth great-grandmother. Her dark hair was neatly tucked under a linen cap, her nimble fingers mending homespun wool while keeping a watchful eye on the hearth.

Beside her sat their nineteen-year-old daughter, Jeanne Angélique Voisard—the author’s fourth great-grandmother. Jeanne Angélique’s youth had been forged in the crucible of the revolutionary years. She had watched the old curate driven from his pulpit, seen the months renamed to honor frost and flora, and lived through the harrowing month of Thermidor when her little four-year-old cousin, Marie Joséphine Brijéchoux, had slipped away in the arms of her aunt Jeanne Marie.

Yet life in the mountains refused to surrender to grief. Down along the cart road connecting Montécheroux to the parish of Glay, young Joseph Faivre—the author’s fourth great-grandfather—was often seen driving his team of draft horses. When their eyes met outside the communal fountain on market days, the future of the lineage was already quietly being written.

On the tenth of May, 1802—recorded under the Consulate calendar as 20 Floréal an X—a solemn family duty summoned Jean Germain from his fields.

His elderly aunt, Marie Magdeleine Voisard, had passed away in the quiet hours before dawn at the age of seventy. She was one of the last living links to the old era—a daughter of early patriarch Étienne Voisard, born when the crown of Louis XV was still young and the Jura was a secluded haven of Protestant and Catholic artisans living side by side.

Stepping out into the crisp mountain air, Jean Germain walked down the lane toward the house of his wife’s cousin, Pierre Claude Loichot. Loichot, a sturdy forty-six-year-old plowman whose Lachat forebears had cleared these hills for two centuries, met him at the gate.

“It is time, Pierre Claude,” Jean Germain said quietly, adjusting his woolen coat. “We must go to the mairie for Aunt Magdeleine.”

“I am ready, cousin,” Loichot replied, wiping the soil from his boots. “Abram will have the ledger open.”

Together, the two men walked through the village center. They climbed the stone steps of the municipal house, where Jean Nicolas Abram sat behind the wide registry desk. Abram was a changed man since the summer epidemic had taken three of his own children, but he carried his sash of Maire with unyielding dignity.

“Good morning, Jean Germain. Pierre Claude,” Abram greeted them, rising slightly. “You come on account of the old aunt?”

We do, Monsieur le Maire,” Jean Germain answered. “Two o’clock this morning, in her bed. She went peacefully.”

Abram took up a fresh goose quill, dipped it into the iron-gall ink, and carefully inscribed the official words onto the thick rag paper of the Year X register:

Du vingt du mois de floréal an dix de la République… Acte de décès de Marie Madelaine Voisard… âgée de soixante et dix ans… fille de feu Etienne Voisard. Sur la déclaration à moi faite par le Citoyen Jean Germain Voisard, Cultivateur, neveu de la défunte, et par le Citoyen Pierre Claude Loichat, Laboureur, ami de la défunte…

When Abram turned the broad ledger around, Jean Germain leaned over the desk. With steady, practiced strokes, he wrote his familiar abbreviation: J G Voisard.

Directly beside him, Pierre Claude Loichot took the quill, penning his name in a bold, cursive script: pierre claude loichot.

On that single page, the ink bound the two great ancestral pillars of your family—the Voisards of the high watchmaking plateau and the Lachats of the mountain pastures—into an indelible legal testament.

As Jean Germain and Pierre Claude stepped back into the bright May sunshine, the bells of Saint-Hippolyte resonated faintly across the distant gorge. The dark shadow of the fever had passed. Within a few short years, Jeanne Angélique Voisard would wed Joseph Faivre, and their daughter, Marie Elise Faivre, would be born into this valley. From the hands that filed watch escapements and guided wooden plows through rocky Jura soil, the unbroken chain of life endured—carrying the blood and spirit of Montécheroux across the sea into the chapters of a new world.

Part II: Year-by-Year Historical & Genealogical Analysis (1799–1802 / An VIII – An X)

The death registers of Montécheroux between Vendémiaire an VIII (autumn 1799) and the close of An X (autumn 1802) chronicle a pivotal era in the French Doubs. Locally, this period witnessed the consolidation of the Napoleonic Consulate, the formal establishment of the office of Maire under the Constitution of Year VIII, and the community’s endurance through a devastating pediatric epidemic in the summer of 1801 (Year IX), followed by a return to baseline mortality in Year X.

When cross-referenced against your Unified Voisard–Jourot–Lachat Descendancy Register, these registers document direct ancestral involvement, culminating in the ormal joint appearance of direct ancestor Jean Germain Voisard (5th Great-randfather) and allied kinsman Pierre Claude Loichot/Loichat before the civic authorities in May 1802.

1. Republican Year VIII (September 23, 1799 – September 22, 1800)

Civil Leadership: Municipal Agent Pierre Antoine Tournoux (Agent municipal), followed by the installation of toolmaker Jean Nicolas Abram as the first constitutional Maire.

Total Registered Deaths: 9 acts.

Demographic Profile:

Typical rural demographic baseline dominated by elderly day laborers and seasoned artisans during the harsh winter months: Catherine Billon née Capperoniere (26 Vendémiaire / Oct 18, 1799), Susanne Chauverdot (age 78, 4 Brumaire / Oct 26, 1799), Susanne Billon (age 71, 4 Pluviôse / Jan 24, 1800), Susane Crélerot (age 67, 24 Pluviôse / Feb 13, 1800), Pierre Étienne Bourlier (farmer, age 48, 8 Ventôse / Feb 27, 1800), George Bouton (wheelwright, age 62, 16 Ventôse / Mar 7, 1800), and Germain Braichet (age 66, 7 Floréal / Apr 27, 1800).

Only a single pediatric death occurred all year: infant Jacques Huguoniot (6 months, 8 Fructidor / Aug 26, 1800).

Witness & Kinship Dynamics:

Close mutual assistance is seen between schoolmasters Pierre Nicolas Lanoir and Jacques Frédéric Perdrizet (acting as civic witnesses and Protestant pastoral guides), who appeared alongside master watch toolmakers Étienne Guental and Pierre Bourgoin.

2. Republican Year IX (September 23, 1800 – September 22, 1801): The Pediatric Contagion

Civil Leadership: Jean Nicolas Abram (Maire).

Total Registered Deaths: 35 acts (representing a catastrophic 388% increase in village mortality).

Epidemic Progression:

Baseline Phase (Vendémiaire – Germinal): Only 3 deaths across six months (Catherine Quélet, age 74; infant Mariane Vernier, 3 months; and infant Pierre Nicolas Guental, 1 month).

Outbreak Phase (Floréal – Prairial / May – June 1801): An acute eruptive fever invaded the valley, striking the Mayor’s home first: Anne Abram (age 7) on 20 Floréal, followed by her brother Pierre Christophe Abram (age 2) on 25 Floréal. Eight more children died across June (Prairial).

Crisis Peak (Messidor an IX / July 1801): 13 deaths in 30 days. The Mayor lost a third child (David François Abram, age 21, toolmaker). The Guental, Bourgoin, and Petitjeune/Méquillet households suffered multiple losses.

Thermidor Peak & Direct Voisard Family Impact:

Act MTC-AN09-D26 (1 Thermidor an IX / July 20, 1801): Four-year-old Marie Joséphine Brijéchoux passed away at 9:00 PM. She was the daughter of day laborer Ursanne Brijéchoux and Jeanne Marie Voisard (IND-022). Because Jeanne Marie was the full sister of direct ancestor Jean Germain Voisard (IND-021, 5th Great-Grandfather), little Marie Joséphine was your first cousin 5 times removed.

Subsidence (Fructidor an IX / August – September 1801): The contagion waned after claiming three additional children (Jacques Huguoniot, Pierre Mélières, Christine Richard) and innkeeper Daniel Petit (age 48).

Epidemiological Finding: 32 of the 35 victims were infants and children under age 10 (a 91.4% child mortality concentration), confirming a malignant epidemic of measles (rougeole) or scarlet fever (scarlatine).

3. Republican Year X (September 23, 1801 – September 22, 1802): Return to Baseline & Ancestral Nexus

Civil Leadership: Jean Nicolas Abram (Maire).

Total Registered Deaths: 7 acts.

Demographic Profile:

Mortality normalized completely back to baseline, with passings occurring primarily among older residents: George Quélet (cutler, age 78, 4 Pluviôse / Jan 24, 1802), Jean George Crélerot (mason, age 72, 8 Pluviôse / Jan 28, 1802), Susanne Vernier (age 17, 29 Pluviôse / Feb 18, 1802), and Catherine Quélet (age 47, 1er Jour Complémentaire / Sep 18, 1802).

Post-Epidemic Maternal Mortality: The register opened on 21 Nivôse an X (Jan 11, 1802) with thirty-five-year-old Catherine Conraud, wife of Jean Nicolas Crélerot, succumbing in the winter cold just five months after the death of her two-year-old son in the summer fever.

The Direct Voisard–Loichot Nexus (Act MTC-AN10-D06):

On 20 Floréal an X (May 10, 1802), seventy-year-old Marie Magdeleine Voisard died at 2:00 AM. She was a daughter of early ancestor Étienne Voisard (IND-001) and paternal aunt to Jean Germain Voisard.

The act was declared in person by her nephew, Jean Germain Voisard (IND-021, 5th Great-Grandfather), described as a Cultivateur residing in Montécheroux, and his friend and allied kinsman Pierre Claude Loichot (Loichat), Laboureur.

Both men personally signed the register before Mayor Abram: Jean Germain using his characteristic signature J G Voisard alongside pierre claude loichot. This record formally binds the living paternal Voisard and maternal Lachat/Loichat ancestral lines on a single leaf of the official civil record.
