Much attention has been paid to systems that survive common envelope evolution, but little to those that merge. We present the results of population synthesis calculations in which a giant star and its lower mass companion merge during common envelope evolution. The subsequent evolution of the merger product is followed until the present epoch. We discuss possible present-day observational counterparts to these merged objects, such as single sdB stars and lithium-rich giants.
