⚜️ ORIGIN
The name FRESNEAU evokes a place planted with ash trees (frênes), a common toponymic formation in Poitou-Charentes (variants: Fresnaud, Fresnault).
The earliest mentions are concentrated in the 16ᵗʰ century in notarial acts from Poitiers and Niort.
Connected to fiefs such as CHÂTELET-FRESNEAU or Nuaillé (Saintonge, from 1370).
Following regional etymological patterns (consistent with Albert Dauzat), it designates a wooded estate or a small river bordered by ash trees.
⚜️ The FRESNEAU family from Poitou
The de FRESNEAU (or du FRESNEAU) family, a noble house of Poitou origin, appears in the archives as early as the late Middle Ages as a line of minor landed nobility rooted in the historic regions of Poitou, Saintonge and Vendée (today’s Vienne, Deux-Sèvres, Charente-Maritime and Vendée).
The surname, derived from Latin fraxinus (ash tree), refers to a wooded toponym or an ash grove, typical of Picto-Charentais formations with the suffix -eau. Attested since the 16ᵗʰ century around Niort, Poitiers, Guitinières and Châtellerault, it spread through alliances and migrations toward Touraine, Anjou, Brittany and even the colonies (French Guiana).
The FRESNEAU distinguished themselves through rural seigneuries (Marigny, La MOTHE-FRESNEAU, Nuaillé, La GATAUDIÈRE), ecclesiastical, notarial and administrative offices, as well as scientific and military contributions in the 18ᵗʰ century.
Their history reflects the rise of a nobility of extraction or of the robe, marked by feudal homage, ruin following the Wars of Religion, and dispersion after the Revolution.
This notice integrates Poitevin archives (Saint-Benoît, Poitiers notarial registers), armorials and recent genealogies.
⚜️ LA MOTHE-FRESNEAU (14ᵗʰ–18ᵗʰ centuries)
Fortified motte from the 14ᵗʰ century, acquired by the FRESNEAU in the 16ᵗʰ century by alliance, inheritance or purchase (fiefs of La MOTHE-FRESNEAU and Nuaillé in Saintonge, mentioned since 1370).
Linked to the Lords of Lusignan (12ᵗʰ–13ᵗʰ centuries), later passing to the royal domain (14ᵗʰ c.).
First mention of the castle in 1408 (homage of Symon Mourault to the Duke of Berry).
Ruined after the Wars of Religion (late 16ᵗʰ century).
Around 1670, René du CHÂTELET-FRESNEAU (born c. 1640-1650, a Lorrain-Poitevin nobleman) inherited or purchased it.
Notarial acts from Poitiers (1685) record land repurchases for 4,000 livres and repairs to the estate (1683-1687). Styled “noble and powerful lord,” with rights of high and low justice.
Sold around 1690-1700 to the Nuchèze family due to debt; the branch became extinct in the 18ᵗʰ century.
⚜️ FRESNEAU, Lord of La GATAUDIÈRE
The lordship of La GATAUDIÈRE (or GATEAUDIÈRE, in Charente-Maritime, near Marennes in Saintonge) is a noble estate attested since the Middle Ages, under the fortress of Broue (14ᵗʰ c.), with military duties, a windmill, warrens, and a feudal manor.
In the 17ᵗʰ century, it passed to the FRESNEAU through marriage: François FRESNEAU de La RUCHAUDERIE (esquire, Secretary to the King at the Cour des aides of Guyenne, † c. 1720) married Anne Regnauld in 1700, who brought the fief as her dowry.
He adopted the title Lord of La GATAUDIÈRE, where their son, the renowned François FRESNEAU de La GATAUDIÈRE (1703-1770), was born.
This latter, mathematician and engineer to the King (officer of the Corps of Engineers), inherited the domain in 1751 from his mother and rebuilt it as a château in 1749, blending Louis XIV, Regency and Louis XV styles. Returning from French Guiana in 1748—where he had fortified Cayenne and discovered Hevea latex in 1747, laying the foundations of synthetic rubber with a memoir of 1763—he carried out pioneering botanical experiments there, introducing the potato into France in the 1750s, long before Parmentier.
Married in 1738 to Cécile Solin-Baron, he had eight children, only one of whom survived:
– Charles Jean-Baptiste FRESNEAU, whose daughter Anne-Julie (1775-1848) married in 1794 General François de CHASSELOUP-LAUBAT (1754-1833), commander of Napoleon’s engineers.
Thus, La GATAUDIÈRE passed to the CHASSELOUP-LAUBAT, then to the MURAT family (descendants of Joachim Murat), and remains today the property of Prince Achille MURAT de CHASSELOUP-LAUBAT.
This fief illustrates the noblesse de robe of Saintonge, uniting royal service, science, and military heritage.
