Is it true that this woman is 191 years old and lives in Nigeria?

The photographs purportedly show  a 191-year-old woman named "Mama Esifiho" (also spelled Mama Efisho).

According a great great grandson of the woman, Mr. Avuefeyen, the woman who is about two centuries old ‘lives in Ellu (Edhemoko, Akaluba Street, Ellu in INLG) in Delta State.’

While questioned on the veracity of this claim, Mr. Avufeyen claimed that that she witnessed the birth of his grandfather.

If his claims are true then, Mama Efisho is most likely Nigeria’s oldest woman alive.

Given that the oldest living person in the world is 116 years old, and the oldest person in recorded history lived to be 122, it is either this story is a hoax or Mama Efisho has exceeded the longest known human lifespan by an astounding 57%.
