The nature of language diversity in small, isolated communities is considered by examining a unique sociolinguistic situation in which a one African-American family has resided for over 130 years on a small island community located off the Southeastern coast of the United States. The Anglo-American community maintained a distinctive dialect due to their isolation from the mainland United States, while the sole African-American family maintained a variety heavily influenced by African-American Vernacular English. Although some assimilation to the surrounding Anglo-American variety has taken place, a number of salient African-American Vernacular English features are still used by the single African-American resident of the island. At the same time, the most marked items of the Anglo-American Outer Banks variety have not been assimilated, thus demonstrating the symbolic exclusion of the African-American speaker from the Anglo community despite her life-long residency.
