GaDangmes of Ghana (History of the Ga People) Ga is the language and the name of the tribe. The Ga people are from Accra the capital of Ghana. They are estimated to be well over 300,000 Ga people in population in the whole of Accra. Ga is a Kwa language, part of the Niger–Congo family. It is closely related to Adangme and together they form the Ga-Dangme branch within Kwa. The origin of the Ga-speaking ethnic group stems from the 16th century when the Ga people migrated from East Nigeria. Rumor has it that the Gas first started out, many years ago, in Israel.
