Dodinas Brandybuck was the fourth child of Gorbadoc Brandybuck (S.R. 1260-1363) and Menegilda Goold. He was born between S.R. 1308 (after his brother Saradas) and S.R. 1313 (before his sister Asphodel). Because he was not among the guests of Bilbo's Farewell Party, he must have died before September, S.R. 1401.
