Abstract
We have identified six T Tauri stars, at least three of which are double, t hat are members of the nearest region of recent star formation, the TW Hydr ae association. The newly discovered systems are mostly located south and e ast of and farther from Earth than most previously known members, thus, the full extent of the association is not yet established. Including secondari es in multiple star systems, the association is now known to include more t han 30 T Tauri stars and a brown dwarf. We compare the TW Hydrae associatio n to four other young nearby associations.
