An Inca princess was married to the captain who captured her uncle, their daughter got a Spanish marquisate with the Inca estate of Yucay, and Inca claimants fought for it after the line died out

Sayri Túpac, Inca of Vilcabamba, left his mountain state in 1557 after the viceroy agreed to give him 17,000 castellanos of rent and the valley of Yucay. He died at Yucay in 1560. His daughter Beatriz Clara Coya was married to Martín García de Loyola, the Spanish captain who had captured her uncle Túpac Amaru, the last Inca of Vilcabamba^†. Viceroy Toledo had Túpac Amaru executed in Cuzco in 1572^†. Philip II, Markham writes, then rebuked Toledo: "I sent you to serve kings; and you went to kill kings." Loyola became governor of Chile and was killed in an ambush. On 1 March 1614 Philip III made their daughter, Ana María Lorenza, Marchioness of Santiago de Oropesa, with the Yucay valley and a yearly income of 10,000 ducats. She married into the Borja family of Gandía. Her line ended in 1741 and the title reverted to the Crown. Juan de Bustamante Carlos Inga, a mestizo from Cuzco claiming Inca descent, sought the marquisate at the court of Ferdinand VI and failed. From 1776 Diego Felipe Betancur and José Gabriel Condorcanqui, later the rebel Túpac Amaru II, litigated over Inca descent before the Audiencia of Lima; the case was never decided and many papers were destroyed after the 1780 rebellion^†. Spain revived the title in 1981 for a Spanish collateral descendant. The Yucay lands stayed with the state.
