For what it's worth, I don't think he messed up Saarinen (or, at least, messed it up enough to garner a neg), but he did turn Eero into Eeno. All the more reason not to give first names unless you have to.
"This Beverly Cleary girl has a mom & dad; Helen Hunt Jackson's 1884 character of the same name does not"
I guess "of the same name" means that everything you give in your response must apply to both characters to be correct. Since Helen Hunt Jackson's character didn't have the last name Quimby, it couldn't be taken.
