They were received at the courts of sultans, kings, and princes, and often were employed as ambassadors, envoys, or agents.

Among other names mentioned are those of Belmonte, Nasi, Francisco Pacheco, Blas, Pedro de Herrera, Palache, Pimentel, Azevedo, Sagaste, Salvador, Sasportas, Costa, Curiel, Cansino, Schönenberg, Sapoznik (Zapatero), Toledo, Miranda, Toledano, Pereira, and Teixeira.
