 Later, the family became traders, explorers and politicians.The family's previous Venice residence, the Ca' da Mosto, which can be seen from the Rialto market by the Grand Canal, was lost through marriage in the 17th century, when Chiara da Mosto, a female member of the family, married four times, with each husband dying of natural causes – thus enabling her to become one of the wealthiest people in Venice.Unfortunately for the da Mosto family, the childless widow had a falling-out with them and on her death in 1603 she left everything to Leonardo Donà dalle Rose, a nephew of her second husband, who went on to become Doge.
