Got a potential thread; There was one noble de Urrea family in Zaragoza between 1600 - 1750. Don Antonio de Urrea (born 1675 catalayud, child of Don Fernando de Urrea y Aragon and Dona Isabel Tomas Jayme) married Dona Josefa de Burgos (child of Don Pedro Francisco de Burgos and dona Ursula Alfay)in 1704 and got at least following children;

1. Josefa Isabel Manuela de Urrea b. 1715 (Zaragoza)
2. Manuela Josefa Ramona de Urrea b. 1719 (Zaragoza)
3. Francisca Ignacia Ramona de Urrea b. 1721 (Zaragoza)
4. Antonio de Urrea y Burgos b? (+ 1736). Married to Dona Rosa Mendieta (children; 1. Valero Montengon de Urrea, 2. Francisca Ignacia de Urrea, 3. Lamberto de Urrea)

If anyone knows more about this family it would be very intersting. In particular did Antonio and Josefa have more children and any linkage to conde de Aranda (Ximenez de Urrea)

In case someone is interested in this family I have quite a bit of more info.
