The North Frisians are a linguistic and cultural minority living in Northern Germany. The North Frisian migration to the USA took mainly part from the island of Föhr after the two world wars. This paper deals with the descendants' identity (2nd to 4th generation) in New York City and Petaluma, CA. It states that North Frisian identity in the US today depends on two main factors, which are supposed to have their roots in the social and linguistic conditions in North Frisia: (1) the multilingual background -- Föhr Frisian descendants typically have language skills in three heritage languages, High German, Low German and Föhr Frisian -- and (2) the multicultural background. The paper shows to what extent North Frisian plays a particularly important role in emotional terms for the descendants even up to the fourth generation.
