I don't know for sure, but for him I would definitely think a tiger. As far as Fleur's Patronus . . . a lioness? Yea, that's it. My thoughts are Bill's Patronus is a tiger and Fleur's is a lioness.

EDIT: I did mean lioness and not tigress, by the way. (If that's even the correct term.)

I haven't found anything canon about either of their Patronuses.
