I know that this post is very old, but I thought I'd add my thoughts as a 19th century poetry person, versus someone who is interested in the 18/19th century novel (as I think you, strokeofmidnight, are?).
I had a problem identifying romantic into Victorian poetry people with whom I'd like to work at Cornell, NYU, and even Duke (their main romanticist is more interested in continental romanticism(s) and only did some of his earlier work on Wordsworth). Either way, I'd second everyone's advice to look at faculty research beyond their general interests. In my case, a professor who claims to be interested in "romantic literature" could have written articles on Shelley 10 years ago, but has since concentrated upon the applications of 19th century legal theory. This is all well and good, but if you want to work with someone active in the field when YOU'RE becoming active in the field, it might become problematic. I'd also second the exhortation to find a school where you could imagine yourself working with more than one faculty member. After all, shit happens where professors leave or change interests, so you want to have a few options. And your own interests will grow and transform as well.
Anyway, to conclude this barrage of unsolicited advice, I'd say that programs with good 19th century poetry programs (either British or American) would include: UVA, Duke (not for me, though!), Princeton, Rutgers, Stanford, Michigan, WashU, etc.
