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.
You don't go back to a great grandfather to show that first cousins are also second cousins through him. The children of first cousins are, to each other, second cousins. Their children are third cousins, etc. Working backwards it would be logical to call brothers zero cousins.. Every society has special names for certain close relationships and resorts to numbers only for the rarer or less important relationships.
