The name of the founder of the place is called Iwíntólú 'the worship of the fairies as a divinity is up to'. After Òwu War that ensued and destroyed Òwu town, Iwíntólú's parents left Òwu town for Ìbàdàn. They left Ìbàdàn again after a quarrel happened in Ìbàdàn and travelled to Ìwó town. It was at Ìwó town that Iwíntólú's parents gave birth
to him. When the quarrel that happened back then at Ìbàdàn was resolved, Iwíntólú's parent returned to Ìbàdàn. During that year, they arrived at Akínyo's Compound in Màpó at Ìbàdàn.
However, there was a certain powerful man
in Akínyo's Compound whose name was
Ọmọtọ̀ṣọ́. Since he and Iwíntólú were both
powerful men, he told Iwíntólú that both of
them could not live together as there would
always be tussle for supremacy between them. Ọmọtọ̀ṣọ́ then gave Iwíntólú a piece of
advice that he should change his location. This
was how Iwíntólú and his parents moved
from Akínyo's Compound to the place called
Iwíntólú was a very powerful man who had
many charms and performed many wonders
at the war-front. It is actually said that he
could transform himself into a bird. At war,
there were always alarming gun shots
sounding tremendously both on the right and left and he would transform to a bird.
Whenever he turned to a bird, he would
mingle with the other birds in the forest and
chew grains with them. The other warriors
would then fail to recognize or identify him as
Iwíntólú and since their intent was not to hunt for birds, they would just ignore the birds
chewing. It was here Iwíntólú would hide until
convenient time for him to change back to a
human to continue fighting at war.
After the war, his allies and friends who knew
him well and his ways at war would start
praising him thus; a bá ẹyẹ rún ọkà bí àrìrà which literally means 'he who chews grains with the birds skillfully and quickly like
lightning'. This act of Iwíntólú led to the
saying that “let us visit Iwíntólú who chews
grains with the birds”. Gradually, people
started referring to this place, i.e. Iwíntólú's
place, as Bẹ́yẹrúnkà. This led to the naming of this place as Bẹ́yẹrúnkà.
