Irish Traveler descent and inheritance is bilateral, although the children, as is the general custom in the United States, take the father's last name. Travelers recognize each other as close relatives compared to outsiders. Kinship responsibilities within the group, however, are usually limited to immediate family members and first and second cousins. Working partnerships for Irish Traveler men are varied and may include Fathers and sons, brothers, or fathers-in-law and sons-in-law. Cousins become partners only when a more immediate family relation is absent. Beause of the residential pattern of each group of Irish Travelers, whenever a party or ceremony involving a Traveler occurs, the entire village is invited.
