Amrothros (T.A. 2120 - T.A. 2254) was the fourth and last child of Adrador, making him the younger brother to three older sister. Ruling Dol Amroth for 48 years as the third Prince, Amrothros carried on his father's works. In his time, many villages were raised spanning from Dol Amroth to his father's port-town of Sarlond to accommodate his spreading people. He wedded one of the Steward's close relations to continue the bond between the two lines.
