Observed features of the galaxies in the Magellanic plane might
suggest that the Large Magellanic Cloud (LMC) was the largest galaxy
in a group of galaxies that entered the Milky Way system at late
times.  Many of the brightest dwarf galaxies of the Milky Way might be
part of this system. Half of the missing satellites might be part of
the group, so they survive more easily in such systems than in parent
halos as large as the Milky Way. There is further support for such a
notion in the properties of the dwarfs in M31 as well as a second
possible group that is associated with the Fornax dwarf.  We find that
the specific angular momentum of the LMC and its group is greater than
the disk of the Milky Way and the total angular momentum of the system
is comparable to the product of the entire mass of the Milky Way
system times the specific angular momentum of the disk.  This tilts
the angular momentum vector of the Milky Way system by 45 degree and
has strong implications for comparing cosmological simulations of
angular momentum to present day galaxies.
