Till here the genealogy of Queen Mathilde is publically known. According to Baron de Herckenrode the line goes further to Rosso Van Udekem, but Guido Joris, who has studied the House of Udekem in depth (and has given his results to the family d'Udekem d'Acoz), says a link to Reinier, who founded the cloister of Gemp, is easily made. What is sure is that the origin of the House of Udekem can be found in the region of Leuven and that the original 'Udinga Haima' (in Korbeek-Lo), from which the Udekems descend, was a settlement of the offspring of the Frankish Baron Udo.
