It's not that easy, since people do marry second and third and fourth
(etc.) cousins, and the larger the pool of related people, the more
likely that people will marry distant relations (particularly if
there's not a lot of mobility, and thus not a lot of choice in
mates). This reduces the number of possible descendants, because with
each intermarriage, there are fewer resulting branches: conceivably
one person could give rise to a stable population of, say, 10,000, all
of whom live in the same county, and all of whom marry other
descendants of that person, so that the number of descendants never
increases into the billions. With royalty, which tends to have
daughters that marry abroad, and where there is a good deal of social
pressure to produce progeny, family trees are probably a bit
'bushier'; and there are countervailing pressures as well, e.g.
inbreeding (as with the Habsburgs), and limitations based on class
(e.g. "ebenbürtigkeit") and religion. And geography plays a role too
-- there are perhaps millions of people in Great Britain, Ireland,
Canada, Australia, New Zealand, and South Africa descended from
William the Conqueror; many, but fewer, in the Netherlands, France, or
Spain; fewer yet in Poland, Hungary, or the Balkans; very few in
Arabia or Japan; and virtually none in Tibet or Mongolia (tourists and
transients aside).
