Mitt Romney
I'm not sure if it's really notable enough that Mitt Romney is a PPP descendant. Any sixth or seventh generation Mormon could point out that a great deal of the population in the Salt Lake Valley alone carry his bloodline. Heck, I am but one of his many many many *many* descendants. Why? He was a polygamist with many wives who had many children. Couple that with how many generations between him and the latest generation and you have a whole bucketful of Pratt blood running about. I don't think it's really significant that Mitt Romney is his great great grandson.

I found this out in 4th grade back in Welby Elementary in South Jordan when my teacher asked the PPP descendants to raise their hands and well over a third of the hands went up, including mine. PPP descendancy isn't that uncommon in Utah, and really isn't that noteworthy.
