Although historically the original inhabitants of the area were Yoruba speaking, there seems to have been a wave of migration from the region of Allada further west in the 1600s, which brought Te-Agbalin (or Te Agdanlin) and his group to the region of Ajashe in 1688. This new group brought with them their own language, and settled among the original Yoruba. It would appear that each ethnic group has since maintained their ethnic idenitites without one group being linguistically assimilated into the other.
