I don't want to hijack the thread, but would like to surface another such organization which I am aware of - Yuwa [1], which operates in India.
It was founded by Franz Gastler [2] when he visited India a couple of decades ago and spent time in some _really_ rural parts of the country. I'm proud to call him a friend, and have volunteered myself at the Yuwa School to teach math/CS. Through this school, girls have ended up at Harvard (!!) with scholarships, who would've never stepped out of their villages and probably ended up as child brides. I usually introduce him to my compatriots as the firangi who's done more for our country than anybody else I know!
Just a heads up (in case you're able to let the founder know) that the "Fundraise" and "Pledge" buttons on that page lead to 'page not found' error. "Give monthly" button works though.
