We present a catalog of 424 common proper motion companions to Hipparcos
stars with good (>3 sigma) parallaxes, thereby effectively providing new
parallaxes for these companions. Compared to stars in the Hipparcos catalog,
these stars are substantially dimmer. The catalog includes 20 WDs and an
additional 29 stars with M_V>14, the great majority of the latter being M
dwarfs.Comment: Submitted to ApJS, 20 page
