A fourth cousin is someone in a family who shares the same great-great-great-grandparents. First cousins share the same grandparents and second cousins have the same great-grandparents. Ordinal numbers of cousins are in the same generation as each other. For instance, all of the children of siblings are first cousins.
Under a simple model where a family has 2-3 children, you would have 190 third cousins, 940 fourth cousins and a whopping 4,700 fifth cousins. Going back to 8th cousins (or 9 generations back to a common ancestor), the model we developed predicts you would have over half a million 8th cousins!
