<P> The lineage of La Cerda continued throughout the Middle Ages and was constituted as a noble house of the first rank, playing a leading role in Castilian politics . This line, like others from the Civil War of mid-fourteenth century, continued through the female line to shift the family heirloom until Dona Isabel de la Cerda, married Bernardo de Bearne, first Count of Medinaceli . </P> <P> Currently, the House of La Cerda stems into several noble families: the House of the Dukes of Medinaceli, as direct heirs of Fernando and Alfonso la Cerda, and its minor Ducal House of Parcent . From the House of Parcent (dukes since 1916) stem the minor noble houses of the Marquissates of Eguaras (in the House of La Cerda since 1799) and of Cañada - Honda (created in 1893 for Emilio Drake De La Cerda, grandson of the Count of Parcent) </P>
