  High precision astrometric data have enabled us to determine the trajectories
through the Galactic potential for a growing number of pulsars. This has
resulted in the discovery of a pulsar pair (B2020+28 and B2021+51) that has a
common origin in the Cygnus Superbubble or in one of its related OB
associations at an epoch which is comparable with the spin-down ages of the
pulsars. Analysis of the Galactic orbits indicates that the progenitors of the
pulsars had similar masses and were in a binary system, which was disrupted
after the second supernova explosion. The implied pulsar birth velocities are
consistent with the high velocities of neutron stars in general. The initial
spin period of the pulsar that was formed in the second supernova explosion was
approximately 200 ms. A further increase in astrometric accuracy will allow us
to more tightly constrain the birth velocities and the kick velocities that
were imparted by the two respective supernova explosions. Two additional
pulsars in the sample of 24 with parallax measurements may also have originated
in the Cygnus Superbubble.
