Does a person have legal right to Warranty Deed after signing Quit Claim deed?

My parents sold our Michigan home in the early 80's and we moved to another state. They sold it through a land contract. The person they sold it to then sold it to another person through a land contract, before it was paid off. Then that person sold it to someone else, again through a land contract. Still not paid off. The original buyer signed a quit claim deed to the next buyer. Then that buyer signed a quit claim deed to the next buyer. My father knew that the first buyer had sold it to the second buyer. But he didn't know that the second buyer had sold it to the third buyer. And he signed over the warranty deed to the second buyer after the second buyer had already signed a quit claim deed to the third buyer. Did the second buyer have a right to that warranty deed, after signing the quit claim deed?
