I shall invite you on to the family geneaology website I have started for our parents, Mariano and Eleanor Azevedo. Hopefully, we will have out old photos (aren't that many) posted and update our histories.
The only name I ever heard about Tia Cuca's father was "Mr. Perez". But we can research it more if we had more information. Place of birth, time of birth for Tia Cuca.
Yes, I believe there were a lot of "Ignacios" running around. I believe grandmother Narcissa's father was Ignacio Fierro who was born in Spain. So, our "Tio Fierro"--Joe, could have been names after his father?
