When I was a member of the Houston AP, we recommended contacting sorority alumnae and the individual alumnae associations.

The Texas AP's want you to register with them so they can keep tabs on who is going where and to help where they can. They aren't a rec-writing service and they encourage you to get as many personal recs as you can and have those personal recs sent to the rec chair of that particular individual sorority area alumnae association, who puts them together in a packet and mails them all out to the chapter. (But that isn't required-- you can get recs from any alumnae of that sorority and the alumnae can send them to the chapter on their own.)

So yes, she can contact the various sorority Alumnae Associations in San Antonio and ask for their help to meet an alumna of their organization concerning references and info-recs, and ask them to introduce her to other sororities and their alumnae, which they will happily do.

Basically, as with anything else in life, you can't expect the mountain to come to you-- you have to go to the mountain. OP has made a great start and just needs to keep following up and reaching out to people.
