The observation of the D sJ *(2317), D sJ (2460), and SELEX D sJ * (2632) states with properties differing considerably from what was expected has led to a renewed interest in hadron spectroscopy. In addition to these states, non-strange partners of the D sJ states have also been observed. Understanding the D 0 * and D 1 ' states can provide important insights into the D sJ states. In this contribution I examine quark model predictions for the D 0 * and D 1 ' states and discuss experimental measurements that can shed light on them. I find that these states are well described as the broad, j = 1/2 non-strange charmed P -wave mesons. In the latter part of this writeup I discuss the c possibilities for the SELEX D sJ *(2632) and measurements that can shed light on it.
