The main Ga group known as the Tumgwa We led by Ayi Kushie arrived by sea. When the Guan (Lartehs) on the coast saw them on their canoes at sea, they looked like ants. Hence, the Lartehs refer to them as Nkran (ants). Nkran was later corrupted by the Danes to Akra, then to present-day Accra. "Nkran" in the Ga language is "Gaga", thus they also started calling themselves Ga. Due to their sheer numbers, the indigenous Lartehs thus relocated to the Akuapem ridge. The Ga are also part of the main Guan group that started the initial migration from the Nubia Empire.
