As well as being the mother of tragic singer Whitney – who accidentally drowned in a hotel bath aged 48 in 2012 after years of drug abuse – Cissy was an aunt of singers Dionne Warwick and Dee Dee Warwick.

She kicked off her singing career in 1938, joining her sister Anne and two brothers Larry and Nicky in a group called the Drinkard Four.

Cissy’s death was confirmed on Monday by her daughter-in-law Pat Houston who said in a statement: ‘Our hearts are filled with pain and sadness. We lost the matriarch of our family.

‘Mother Cissy has been a strong and towering figure in our lives. A woman of deep faith and conviction, who cared greatly about family, ministry, and community.

‘Her more than seven-decade career in music and entertainment will remain at the forefront of our hearts.’

Cissy’s musical career also saw her join vocal group the Sweet Inspirations, with Doris Troy and her niece Dee Dee.
