Orbital elements have been determined for four stars from the bright star catalog; HD 21018, HD 30021, HD 158837, and HD 190658. The rotation of these stars has been determined, and HD 21018 is shown to be a giant in rapid non-synchronous rotation. HD 190658 is an M2III giant which could fill its Roche lobe and eventually show eclipses. HD 190658 is also a high velocity star (-112.1 km/s) and has the peculiarity of having the shortest period (198 days) of any binary of type M III. It should also be noted that these stars are all members of triple systems.
