This article is from the Mariah Carey FAQ, by Kade Hansson email@example.com with numerous contributions by others.
Mariah was born of a multicultural parentage, with a European descended
mother (Patricia) and a father (Alfred Roy) of mixed South American and
African-American parentage. Alison and Morgan are Mariah's only siblings, and
are significantly older- by ten years.
Alison is the most outspoken of the two, frequently speaking negatively about
Mariah to the gossip press, and perpetually threatening to write a "tell-all"
biography. Alison turned to drug use and prostitution in her teenage years.
Mariah dedicated her debut album to her, but these days the two are bitter
enemies, largely due to a custody battle over Alison's offspring where Mariah
took her mother's side.
Morgan suffered from serious symptoms of cerebral palsy and epilepsy in his
youth, but is now part of the recording industry, CEO of Big Kid Records
(http://bigkidrecords.com). Morgan is currently single, and has no children.
He was briefly married to actress Jeannie Millar in August 1996, but the rest
of the family never met her.
