Columbus's male line extinct.
Luis left two illegitimate children, one a son; but his lawful heirs were adjudged to be the children of Maria de Mosquera, two daughters, one a nun and the other Filipa. This last presented a claim for the titles in opposition to the demands of Diego, the nephew of her father. She declared this cousin to be the natural, and not the lawful, son of Luis's brother. It was easy enough to forget such imputations in coming to the final conclusion, when Filipa and Diego took each other in marriage (May 15, 1573) to compose their differences, the husband becoming Duke of Veragua. Filipa died in November, 1577, and her husband January 27, 1578. As they had no children, the male line of Columbus became extinct seventy years after his death.
The long lawsuit and its many contestants.
The lawsuit which followed for the settlement of the succession was a famous one. It lasted thirty years. The claimants were at first eight in number, but they were reduced to five by deaths during the progress of the trials.
The first was Francesca, own sister of Diego, the late Duke. Her claim was rejected; but five generations later the dignities returned to her descendants.
The second was the representative of Maria, the daughter of Luis, and sister-in-law of Diego. The claim made by her heir, the convent of San Quirce, was discarded.
The third was Cristoval, the bastard son of Luis, who claimed to be the fruit of a marriage of Luis, concluded while he was in prison accused of polygamy. Cristoval died in 1601, before the cause was decided.
The fourth was Alvaro de Portogallo, Count of Gelves, a son of Isabel, the sister of Luis. He had unsuccessfully claimed the titles when Luis died, in 1572, and again put forth his claims in 1578, when Diego died, but he himself died, pending a decision, in 1581. His son, Jorge Alberto, inherited his rights, but died in 1589, before a decision was reached, when his younger brother, Nuño de Portogallo, became the claimant, and his rights were established by the tribunal in 1608, when he became Duke of Veragua. His enjoyment of the title was not without unrest, but the attempts to dispossess him failed.
The fifth was Cristoval de Cardona, Admiral of Aragon, son of Maria, elder sister of Luis. This claimant died in 1583, while his claim, having once been allowed, was held in abeyance by an appeal of his rivals. His sister, Maria, was then adjudged inheritor of the honors, but she died in 1605, before the final decree.
The sixth was Maria de la Cueva, daughter of Juana, sister of Luis, who died before December, 1600, while her daughter died in 1605, leaving Carlos Pacheco a claimant, whose rights were disallowed.
