Good morning, I got up early to read your reply. I couldn't find a Maria Dolores Aldaz but as you may know, some of the names can be complex and include several middle names. I did find a Facundo dating back to the seventeen hundreds. I have a lot of records for individual members of the Aldaz family. The trick is finding the connection of one member to another. The records I have are primarily from the files at Salt Lake City and came from my cousin, Jesse Mortensen. He is from the Mormon side of the family and has a very strong interest in the Aldaz genealogy. I'm sure that Jesse would be happy to hear from you. He is getting on in years and living with family members but has always been generous with his time. My last phone number for Jesse is 801-277-1059.
If talking to Jesse is not successful, I will be more than happy to send you copies of what I have.
