20 Generations
Chart
Every 20 generations could equal over one million different people.
However, due to the custom of past generations marrying within the
family it doesn’t really work out that way. You would always have the
numbers below for each generation, but some of the people would
be duplicates as when 2 first cousins marry, they share the same
grandparents.If you figure 30 years per generation, which in my opinion is more realistic, 20 generations represents about 600 years.
