He was noted chiefly as an orator, and as the father of Ah-shah-way-gee-she-go-qua ("Ashaweia"), who was the only Ojibwe woman ever to earn full ogichidaakwe (warrior) status.

Chief Nenaa'angebi was of the Nibiinaabe-doodem (Merman Clan), according to the Wisconsin Historical Society and the Lac Courte Oreilles Band of Lake Superior Chippewa Indians.

Ozaawindib gave away the twin brother of Nenaa'angebi to the community of the Snake River sub-band of the Biitan-akiing-enabijig ("Border-sitters"), an Ojibwa-Dakota group, in order to make peace with them and to provide them with a hereditary chief.

"Wabashish", the eldest son, succeeded his father as Chief of the Prairie Rice Lake community of the Lac Courte Oreilles Band.

Niigi'o was buried near the west bank of the Red Cedar River on the north end of Rice Lake, Wisconsin.
