If generation 1640 has 32,768 members and 16,384 marriages as we said generation 1665 has 81,920 members, since we

are assuming that no one is intermarrying we do no have to divide by too will then also have 81,920 marriages. If we continue

to assume no intermarrying we can simply multiply by 5 each generation. Generation 1690 would have 409,600 members,

generation 1715 would have 2,048,000 and so on.

If we want to make this easier we take the original number of marriages in 1640 (16,384) and multiply that by 5^15,

essentially multiplying the number by 5, 15 times, once for each generation. This is (roughly) 500,000,000,000,000. Five hun-

dred trillion. And this would just be in the one generation (the cousins no aunts, uncles or 2nd cousins once removed) Since
