Robert Capet de France

Please note that this is a son of Henry of France and Anna of Kiev that did not make it to adulthood. (Therefore it follows that he never had a wife.)

ROBERT de France (before Jun 1054-[1063]).

The Liber Modernorum Regum Francorum names (in order) "Philippum, Hugonem atque Rotbertum" as the three sons of King Henri & Anna, specifying that "Rotbertus inmatura morte decessit"[244]. This is confirmed by the Chronicle of Alberic de Trois-Fontaines which names (in order) "Philippum, Robertum et Hugonam" as the three sons of King Henri, specifying that "Robertus iuvenis mortuus est"[245].
