Antonio Lante Montefeltro della Rovere
Lante was the son of Ippolito Lante Montefeltro della Rovere and Maria Cristina d'Altemps. He inherited his father's titles and became the second Duke of Bomarzo. When the Lante family purchased the comune of Belmonte from the Mattei (presumably on the death of Luigi Mattei in 1675), Lante became the first Prince of Belmonte.
Thereafter, Lante travelled to Paris. While there, in February 1683, Lante married Louise Angelique Charlotte de La Trémouille (1653–1698), sister of Marie Anne de La Trémoille, and they had 6 children. The two returned to Rome but travelled between the two capitals. When Trémouille died in 1698, in Paris, Lante returned to Rome though a number of his children stayed behind and were appointed to various titles by French and Spanish monarchs.
