It's interesting. I trace my family to Antonio U., Juan's brother. Antonio was married to Maria Cheves (1st wife) and Teresa Riel (2nd wife). What's interesting is that Antonio's son (Antonio Asencio U.) was married to Maria Franchesca Armijo. And, their son Santiago Ulibarri married Maria Josefa Duran.So there are Armijo and Duran names in both Juan and Antonios lineage.
