This study examines the transformation of the Ambo people's personal naming system in Namibia due to Christian missionary activity and European cultural influences. Beginning with Finnish Lutheran missionaries in the late 19th century and later shaped by German, British, and South African colonial forces, the Ambo naming system evolved into a dynamic fusion of African and European elements. Through a socio-onomastic and historical onomastic lens, the book explores how intercultural contact reshaped identity, tradition, and linguistic structures. It provides a detailed analysis of name adoption, retention, and adaptation, highlighting the sociocultural and linguistic factors driving these shifts. Additionally, it situates the study within broader discussions of anthropology, church history, and colonial impact on African naming traditions
