Chapter Summary -- Despite significant changes in social and economic life, Maine Acadian family names, religious affiliation, and connection to the land remain potent markers of cultural identity. French language and other expressive traditions further contribute to the distinctiveness of Maine Acadian culture within the United States and serve as windows into the group's worldview. The following sampling of expressive material culture is based on limited fieldwork in the Valley; a thorough analysis will require extended research. This chapter is comprised of brief descriptions of the language, oral traditions, music and dance, foods, textiles, furniture, and architecture of the Upper St. John Valley.
