If you will check the article at Tours, I rewrote the entire section you questioned, I think accomadating your concerns, and asked you on the talk page for your input so if needs further work, I can do so.  I have a 2000 volume library here, adn much of it is on the Roman Empire, which of course includes the Carolinians since the Holy Roman Empire began with Martel's grandson, Charlamagne.   I am sorry, and welcome your input to improve the article.
