She was aged 75.
Her family, in a statement on Wednesday, said the late matriarch, aka Sisi, died on Friday, May 1, 2020.
The statement said, “Sisi Olubunmi was born 75 years ago on the Lagos Island to the families of Mr Gabriel and Mrs Yetunde Olusoga of Ijebu descent in Ogun State.
“She was part of the pioneer set of the prestigious May Flower School, Ikenne, Ogun State in the late 50s.
“Sisi was an extremely quiet, cheerful, and peace loving; a simple fashionable lady who was always wearing her smiles to all and sundry at all times even in deep hurtful pains. She was a humanitarian par excellence and a deep lover of God. A staunch member of the St. Johns Church, Aroloya, Lagos from her childhood, she would be deeply missed by all both young and old.”
The family said burial arrangements would be announced later.
