I have been over this several times with other LeBlanc descendants.
It seems that their is a problem connecting Daniel LeBlanc and some other Acadian families with their ancestor because of the Wars of Religion.
Jarnac (zhärnäk') , town, Charente dept., in the Cognac region, on the Charente River. At Jarnac in 1569 French Catholics under the duke of Anjou (later Henry III) defeated the Huguenots, whose leader, Louis I, Prince of Condé, was killed.
ALPHONSE LE BLANC a descendant of PIERRE LE BLANC, served under CHARLES IX, and took part in the BATTLE OF JARNAC, that the DUKE D'AUJOU, later HENRI III, won over the HUGUENOTS in 1569.
The Wars of Religion [Huguenot Wars] (1562-1598)
Series of French civil wars, pitting Catholics against Huguenots (Protestant nobles and merchants).
Underlying Causes: Religious intolerance, starting with a massacre of Huguenots(French Protestants) by the orders of the Duke of Guise in 1562.
The wars are fought in 1562-63, 1567-8, 1568-70 (including the Battle of Jarnac), 1572-3 (beginning with the Saint Bartholomew's Day Massacre), 1574-6 (including the Battle of Dormans), 1577, and 1580.
In 1585, another civil war (the War of the Three Henri's) involves Henri of Guise and the revived Catholic League, King Henri III of France, and Protestant Henry of Navarre (heir to the throne). Henri III attempts to suppress Protestantism, but the Battle of Coutras (1587) is a victory for Henri of Navarre. Henri of Guise revolts against the king, but is assassinated. The two Henris march on Paris, but the king is assassinated by a vengeful monk. Henri of Navarre becomes king (1589), and defeats the Catholic League at the Battle of Arques (1589) and the Battle of Ivry (1590). The first siege of Paris (1590) is a failure, as is the siege of Rouen (1591-2), but Henry IV then renounces Protestantism and finally enters Paris in 1594.
Spain continues to support the Catholic faction, but following the Battle of Fontaine-Francaise (1595), the Spanish are driven from Burgundy. The Treaty of Vervins and Edict of Nantes (1598) grant political rights to the French Protestants, bringing the war to a close.
