Retoños de España Tomo II

Hello All I waondering where can I find or if anyone can do a lookup on the Flores de la Torre and Flores-Alatorre family! I want to know how Flores Alatorre changed from Flores de la Torre. Also, is it true the patriarch Juan López de Elizalde is "hijo legítimo de Miguel López de Elizalde y Leonor de Aberruza"? Many Thanks! -Daniel
