Mariah had a complicated relationship with her parents Patricia Carey (née Hickey) and Alfred Roy Carey, as well as her two older siblings, Morgan and Alison. With her mother being white and Irish American and her father being half-Black and half-Venezuelan, Mariah was also subject to racism from early on, sometimes from within her own family.

Indeed, Patricia, whose parents were reportedly from Co Cork, was "disowned" from her family after she married Alfred, a Black man, in 1960. The mother and daughter opened up about their experience dealing with racial discrimination as an interracial family - including having their dog poisoned and having someone shoot their window - in a powerful interview wit.
