We continue our campaign of multi-wavelength observations of Fermi-LAT gamma-ray sources at high galactic latitude utilizing the XMM-Newton EPIC-pn (PN) and MOS instruments. The fields of view of both the PN and MOS instruments are approximately 30 arcmin in diameter and yield arc second positional accuracy for significant X-ray point sources. Thus, for Fermi-LAT sources that are not associated with a known source in another energy band, XMM-Newton can efficiently search for possible associated X-ray sources in the several-arc-minute elliptical error regions of the Fermi-LAT sources. We report here on observations of 1FGLJ2001.1+4351, 1FGLJ0614.1-3328 (=PSRJ0614-33), and 1FGLJ2214.8+3002 (=PSRJ2214.7+30). For 1FGLJ2001.1+4351, the XMM-Newton observations reveal a strong X-ray source inside the Fermi-LAT error ellipse with a power law spectrum and a flux of order 5E-12 ergs/cm2/s (0.5-8 keV). In the case of 1FGLJ0614.1-3328 (=PSRJ0614-33) we discuss both new XMM-Newton observations obtained in 2010 and archival observations obtained in 2001. In the case of PSRJ2214.7+30 (=1FGLJ2214.8+3002) we report on the analysis of PN timing mode data for the X-ray point-source at the pulsar position and we characterize its spectral properties as measured by the MOS instruments.
