This database of information on famous Georgia citizens has a great entry on Flannery O'Connor. Its detailed biography of O'Connor is one of the best you'll find on the Internet (besides Shmoop, of course).
…it might look something like this. A Flannery fan has put together a blog of passages and quotes by O'Connor. This delightful site reads as though O'Connor were blogging away from her farm in Milledgeville. There's even a version in Spanish, si tu prefieres.
O'Connor spent the last thirteen years of her life at Andalusia, a dairy farm in Milledgeville. In 2006, the Georgia Trust for Historic Preservation placed Andalusia on its list of most endangered places in the state. The Andalusia Foundation exists to save the farm and promote O'Connor's works.
Before moving to Milledgeville in 1938, the O'Connor family lived in Savannah, Georgia. This site has information about the house and ongoing events related to Flannery O'Connor.
