If each family has 10 kids...
1,900 great grandchildren
19,000 great-great grandchildren
190,000 great-great-great grandchildren
1,900,000 great-great-great-great grandchildren
*That is more than the current population of Nevada.
Now let's see what will happen if each family has 19 kids...
6,859 great grandchildren
130,321 great-great grandchildren
2,476,099 great-great-great grandchildren
47,045,881 great-great-great-great grandchildren
*That is almost 10,000,000 more than the current population of California.
