Herbert II, vicomte de Thouars

Like many of his contemporaries, Viscount Herbert went to Palestine, the first time in 1098. He left with his brother Geoffrey in 1102 as part of the crusade led by the Duke William IX of Aquitaine. His banner was strewn with golden fleur de lys Azure Gules franc area. These arms have remained those of his house, they then become those of the city of Thouars. Many pilgrims died during the journey from Constantinople in Jerusalem. When Herbert wanted to go back to France, he died in Jaffa in 1104. He was buried near the church of Saint Nicolas de Jaffa. He married 1095 to Agnes with whom he had two son, and Herbert Aimery VI.
