The problem here is that the image is so complicated to explain that someone has devised a sort of seven tier graph to show all the various permutations of being a cousin. The graph is very clever, explaining the relationships between First Cousins, second cousins, first cousins one removed and so on. But I’m sorry to say I simply couldn’t explain it in words. My apologies.
