Her dad is a notable fraudster
Well, this is definitely a reason to change your name. According to the Daily Mail, Chanel's father has gone by multiple monikers in the past, including "Christopher Preboth, Dan Ryan, Danford Nmi Dayn-Ryan, Michael David Ryan, David Michael Ryan, and most recently Dann O Ryan." He's been involved in dozens of lawsuits accusing him of defrauding investors out of millions by lying about properties, inflating their value, and then selling them dilapidated buildings. He also masqueraded as a lawyer, but uh, wasn't licensed to practice law in Texas, where he and his would-be clients were doing business.
