The embedding in SU(4)xSU(3)xSU(3) of the well studied gauge groups
SU(4)xSU(2)xSU(2) and SU(3)xSU(3)xSU(3) naturally leads to family unification
as opposed to simple family replication. An inescapable consequence is the
predicted existence of (exotic)color singlet states that carry fractional
electric charge. The corresponding magnetic monopoles carry multiple Dirac
magnetic charge, can be relatively light (\sim 10^{7}-10^{13}GeV), and may be
present in the galaxy not far below the Parker bound.Comment: 10 pages, Late
