can descendants of single couple multiply into large viable population ?

We had argument on IRC recently, whether, genetically
speaking, descendants of the single couple of humans can
grow into viable population ? (the arguments started from
somebody mentioning that [he read somewhere that it
was genetically found that] all native population of
one of continents descended from a single couple.)
Some people argued that it was impossible, that inbreeding
and recessive pairing (correctme) makes the [whole]
population unviable.
Others argued this is possible, because even if some part
of population suffers from genetics defects, sufficient part
of population has healthily mixed genes
But I'm not biologist and I can't really argue for this. So:
can descendant of single couple multiply into large viable
population ?

P.S. I think when animals migrate to remote places, like
to remote islands, there must be cases when single couple
produce viable population. I think this must happen with humans,
too, through the long history of human migrations.
