I already checked with the diocesan archives in N.O., and they don't have records for this. But your idea to check with the archives for the School Sisters of Notre Dame is a good one--I'll try that! I agree that the Catholics were always good record keepers. The reference dept. at the public library in St. Tammany parish have worked with me on this, but even they could not find a specific account in old newspapers about exactly what happened to the land after it was sold for development.
