There is a Bouguereau in Raleigh, NC at the
NC Museum of Art on Blue Ridge Road. I can't find the information online about it - but I think it says it is "attributed to Bouguereau". The name of it is Young Girl Tempted by Eros (I think). It is very large. As I said, I cannot find exact information on it from either the museum site or ARC.
There are also portraits there by Copley (2 or 3). There is one very large family portrait by Copley which, in my opinion, is worth the visit. The rendering of the satin dresses,drapery is amazing.
This museum also has an extensive collection of High Renaissance paintings.
