Hi,

The proper motions of most stars are too small to matter. More importantly, we 
do not know what the values are for most stars. That incidentally is likely to 
change soon as Gaia gets launched later this year and will measure positions of 
a billion stars much more precisely than ever before over a five year period 
through multiple observations.

There are lists of what are called High proper Motion (HPM) stars available 
[see the two stars in the box here, for instance: 
http://nesssi.cacr.caltech.edu/catalina/20130302/1303021210274114807.html - one 
of them is/has HPM].
Information is also available about some "streams" within our Galaxy. 


Cheers,
ashish
