Oooh ... very close, Arvedui. The first one is indeed Faramir. ('mar', which can be a noun meaning disfigurement or blemish, within the letters fa ir - a 'fair outside', and the 'never preferred' referring to his father's preference of Boromir.)
Denethor isn't the other one, though. And, hint: 'last two years' doesn't necessarily refer to the last two years of the person's life. Think what 'withdrawal of good' might refer to.
