Roger
Georges
This name starts and ends with the same letter.
Ok, again, I made a mistake.
Not Boyer, but if you change one letter and rearrange the others, you'll have it.
Those ar 5 letters.
Boyer XXXX_ (4 letters right, none in the right position)
Robier XXXX_- (4 letters right, none in the right position)
Boriet OXXX_- (3 letters right, 1 in the right position)
