Bereir's family has been for a long time highly esteemed in Gondor.

The blade, Amrendil, was given to his forefather by an elf-lord, after the great battle by the end of the 2nd age.
Many tales are told about the sword and how come the elf would give his long time companion blade to the man.
The elf, however, was found dead only 3 days after gifting his blade away,
Amrendil managed to stay a long time in Bereir's family. 
the sword would be passed to the next in line when the former wielder could no longer wield it.
But, every wielder seemed to be cursed by one thing: Pride.
Many died in battle for foolish actions, including, Bereir's elder son.
He blamed himself for the death of the son, for he was the one who put him in the front-line. Even though everyone knew the boy was too green for the task.
Maddened by grief, the man ran away, leaving his younger son, Murendir, behind and succumbed to the drink.
he cursed the sword and vowed to extinguish it from the family line, forever.
He now roams from city to city, from small task to the next. earning just enough for the next pint.
Running from the past.
