What did CINDY JACKSON's father invent to leave her soooo much money in his will?

Ive researched it and theyre nothing that even says the father or mothers name. But if you can find the fathers name then you can research him as a inventor. He must not of invented anything grand seeing as nobodys ever heard of him and his name is never mentioned in anything. She is pretty but she is so sick theyre should be laws against these plastic barbie people getting surgerys. I thought the doctors put them through a physchology review before doing surgerys and as many as shes had why would anyone want to operate on her.
