El Paso, Texas Border crossing records

Saludos a todos,
I am planning a few trips to visit the UTEP special collection dept to see the documents of Cleofas Calleros. This local historian, author became the Mexican Border Representative of the National Catholic Welfare Conference Bureau of Immigration in El Paso in 1926 to 1968. He handled over 1 million immigration cases and from what I have seen of his documents he was a very organized and meticulous Rep. These records were donated to the UTEP Library and have all been sorted by surname and placed in acid free file boxes. Unfortunately the records for letters A-E were destroyed. If you know that your ancestor came thru El Paso e-mail me directly with the names and any pertinent info such as name of state, town of birth, spouse, parents. Remember that women used their maiden name. This info allows me to distinguish from many similar records. I will then get a copy and e-mail them to you. Some of these records have pictures, with these I take a photo and will do the
same. I know that it will be alot of work but I know that I'm fortunate to have these records almost at hand. PLEASE let me know that you are a RANCHOS COUSIN in you subject heading, otherwise I won't open your
e-mail. I know this will take a while and we will have hits and misses so, please be patient. If you make a request I will assume that you are giving me permission to copy your families documents.
Adios PRIMOS
