bejazd, if she is in highschool in Texas now, she has made friends whose moms might have been in sororities, or she has teachers, etc. Last year, I got calls from girls that were friends of my son's, that I hadn't met, asking if I would write a rec or letter of support. I asked them to bring their stuff by and give me a chance to talk to them. I didn't have a problem with writing on behalf of them, although I did want to meet them first. That might be a way for your friend to get her recs.
Local alumni assoc's can help, but she might try the above first.
