Celebrity families

An individual can achieve celebrity on the basis of their profession, accomplishments, or notoriety, without necessarily having any family or social connections to aid them. However, there are families where the entire family is considered to have celebrity status. In Europe, all members of royal families are celebrities, especially when they are associated with a real or perceived scandal. As well, in Europe and in the US, there are artistic 'dynasties', where several members of a family are associated with a profession-typically music or acting.
