Fernald has no entry of its own for nevertheless; he lists it under but, notwithstanding.
Where he writes about it:
However simply waives discussion, and (like the archaic howbeit) says "be that as it may, this is true;" nevertheless concedes the truth of what precedes, but claims that what follows is none the less true; notwithstanding marshals the two statements face to face, admits the one and its seeming contradiction to the other, while insisting that it can not, after all, withstand the other; as, notwithstanding the force of the enemy is superior, we shall conquer. — from notwithstanding
