We have analyzed the archival Chandra X-Ray Observatory data on G 315.4-2.30 to search for a stellar remnant in the southwest corner of this SNR. The search was motivated by the hypothesis that the SNR G 315.4-2.30 is the result of an off-centered cavity SN explosion of a moving massive star, which ends its evolution just near the edge of the main-sequence wind-driven bubble. This hypothesis implies that the southwest protrusion in G 315.4-2.30 is the shocked material of a pre-existing circumstellar structure and that the actual location of the SN blast center is near the center of this structure. We have discovered two point X-ray sources in the "proper" place. One of the sources is interpreted as a foreground active star of late spectral type, while the second one as a candidate neutron star (perhaps a young "ordinary" pulsar). The follow-up observations of these sources will help us to understand their nature and thereby to test the hypothesis of the origin of the SNR G 315.4-2.30.
