In 1967, Alexander Rosa introduced a new type of graph labeling called a "graceful labeling." This paper will provide some background on graceful labelings and their relation to certain types of graphs called "pendant graphs." We will also present new results concerning a specific type of graceful labeling of pendant graphs as well as further areas of research.
