Ernesto Iglesias Almeida, “La Casa de Regodeigón, en tierras do Ribeiro”, pp. 407–415
A local-history article on the Puga and Baamonde house of Regodeigón. It follows Crespo Pozo, Blasones y linajes de Galicia (1982), for the first generations and the family trees in the 1763 lawsuit over the benefice of Regodeigón (diocesan archive of Tui-Vigo) for the later ones, noting that Crespo’s later generations are unreliable. Secondary: links from it are candidates.
