R. Abstract The small group of galactic globular clusters (GGC) (Pal 12, Terzan 7, Ruprecht 106, Arp 2) recently discovered to be significantly younger (by ~3-4 Gyr) than the average cluster population of the Galaxy are shown to lie near planes passing in the vicinity of some satellite galaxies of the Milky Way and through the galactic center itself. Assuming that these configurations represent a fossil record of interactions between the Galaxy and its companions from which these clusters originated, we identified, along one of them, another candidate "young" GGC, i.e., IC 4499, whose color-magnitude diagram is presented. Various hypotheses on the possible origin of "young" GGC are also briefly discussed within a framework where the location on preferential planes may be seen as a general characteristic for the Local Group members.
