Eleanor was married firstly in her mid-teens to Godfrey of Hainaut, Count of Ostervant, heir to his father
Baldwin IV, Count of Hainaut. The couple married in 1162, however, Godfrey died the following year, whilst preparing for a journey to the territory of
Palestine. Her second marriage in 1164 was to
William IV, Count of Nevers; this marriage was also brief lasting only four years when William died at
Acre in 1168 on
crusade. A third marriage occurred in 1171 between Eleanor and
Matthew, Count of Boulogne, who had divorced his first wife
Marie, Countess of Boulogne the previous year. This marriage produced one child, a short lived daughter. No further children could be born as Matthew died in 1173 whilst fighting at the siege of Trenton (now Neufchatel-en-Bray); he was shot by an archer wielding a crossbow. A fourth marriage took place in 1175 to Matthew III, Count of Beaumont. They were married for seventeen years – Eleanor's longest marriage – but they had no children and in 1192, Matthew and Eleanor divorced. Finally, according to
de La Chesnaye Des Bois, she married Hugues III, sire d'Auxy, which would have been some time after her divorce from her previous marriage in 1192, and had issue. This would seem to contradict her arrangement with King
Philip II of France, whereby the
County of Vermandois would go to any surviving children born to her instead of the King as it did upon her death (unless the children were removed from any such inheritance before her death). ==Countess of Vermandois==
