I can agree with you, with that clear a red splotch he should be a tortie, ie being a tabby too - a torbie.
She may be a maine coon of sorts. Or more probably, one of the natural population from those the Maine Coon become pure bred from. THAT natural population are still there... Its why we do see so many Maine Coon somewhat look alikes...My vet told me awhile ago that she's a mainecoon, she's 2.5 yrs old. Her coat kinda looks bangle almost? (will post photos in comments)
