This title was only renovated later in the 17th century: when the 7th
Count of Vimioso (belonging to the 1st Marquis’ lineage) died, King
Pedro II of Portugal, through a special decree, issued on December 13, 1681, legitimated the count's natural and only son, Francisco de Paula de Portugal e Castro (Francis III), as 8th Count, and also granted him the title of 2nd Marquis of Valença.
