  We report the discovery of seven high proper motion stars with proper motions
between about 0.7 and 2.2 arcsec/yr. They were detected in an archival search
using multi-epoch positions in the optical SuperCOSMOS Sky Surveys and in the
near-infrared sky surveys 2MASS and DENIS. The star with the largest proper
motion, is spectroscopically classified as a very nearby (d=8pc) M5.5 dwarf
with Galactic thin disk kinematics. A second star with about 2 arcsec/yr proper
motion, is still lacking spectroscopic confirmation but can be classified from
photometry as thick disk M3.5 dwarf. Three objects turn out to be cool subdwarf
members of the Galactic thick disk or halo, including the first sdM9.5 object,
which represents the currently coolest known M subdwarf, another ultra-cool
subdwarf, of spectral type sdM7.0 as well as an earlier type (sdM1.5) star. The
latter has an extremely large space velocity with clear halo kinematics. Two
objects show featureless spectra typical of cool white dwarfs. One of them is
probably a very nearby (d~4pc) thin disk object and may be the nearest isolated
white dwarf, the other one has thick disk kinematics.
