KLEVE Thierry

Abt 1215 - 1245  (30 years)

• Name	KLEVE Thierry
  Birth	Abt 1215	Brabant, Belgium
  Gender	Male
  Death	24 Mar 1245
  Notes	Biography Although he was the eldest son, Thierry's death before that of his father circa 1260 meant that he did not inherit the title of Count of Cleves which instead went to his younger half-brother Dietrich. Research notes Seigneur de Dinslaken de Cléves In 1247 archbishop Conrad of Cologne dissolves his marriage to Elisabeth of Brabant, on the grounds of consanguinety in the third degree (although their common descendance seems to be from Berenger of Sulzbach, would be the fourth degree).[1][2] The above biographical notes originally included with this profile are confusing but would make greater sense if they referred to his wife Elisabeth's second marriage with Gerard of Wassenberg. Thierry had died circa 1245 and Elisabeth remarried shortly thereafter. The relationship between Elisabeth and Gerard was second cousins (as presented here on WikiTree); a closer connection than had existed between Elisabeth and Thierry. The notes on Cawley's Medieval Lands webpages suggest this was the actual case.
