Javier, It has been a long time between posts (10 years).
I came across a historical document while searching for info on Nicolas Perez Gavilan Echeverria, the second Bishop of Chihuahua who you and I discussed. This has to do with Luis Terraza. I remembered that you had mentioned this family and thought, as this was a obscure document that you may not have come by it and that it may be of some interest to you. This was origanilly in Spanish.
I will provide the link and the paragraph mentioning Luis Terraza.

Among those invited are Sisniega Frederick Henry C. Creel, Luis Terrazas, Severo I. Aguirre, Silvestre Terrazas, and some priests of the diocese and several people who accompanied the bishop from Durango. (Comprehensive review in The North, Thursday 29 may 1902 and El Correo de Chihuahua, 29 may 1902)".
I hope this is of interest to you.
