The Keys of B-flat, E-Flat, A-Flat, D-Flat, G-Flat, C-Flat, and F-Flat major all contain the note E-flat. F-flat major is a key which only exists in theory and not in practice, since there is a double flat in that scale (subdominant). The major scale with the most flats is C-flat major - with all seven flats.

E A major second is equivalent to a whole note, or two semitones, and two semitones down from G-flat (which is enharmonically equivalent to F-sharp) is E, although it might be written as F-flat depending on the key signature. F-flat, E to G-flat would be a diminished 3rd, not a major second..
