Who is Timothy Pommeroy from Stern Men and what is their importance?

The fourth and quietest of the seven sons of Ira and Rhonda Pommeroy, Timothy grows up to be a decent person, working as sternman on Len Thomas' boat. Timothy closely resembles his late father and tolerates his hotheaded boss, working quietly with his back turned. Timothy keeps only whiskey money for himself, giving the rest to Rhonda, with whom he lives. He drinks all night, alone.
