I don't know...this is an issue I have been chsing for years. I have found several lines that came over from Spain, however, I have not been able to find who or when they came from Spain. Form the rocords I have, I feel that most of the Spanish have inter-married with Native Americans in that area. I will look again and see if I can come up with something.
I am astounded to hear of a De Anza expedition!! Will you share that connection with me?? I know that the Bojorques and Romero located in the San Jose area. I found a plaque downtown honoring them. I know I have a photo of it somewhere. Thanks for your inquiry...my direct email address is firstname.lastname@example.org
. Let's keep in touch...afterall, we are cousins!! Karen Sacco
