In James Joyce's, The Dubliners (in the story 'The Three Sisters'), give four characters in the short story and a brief description of each of them.
You must mean "The Sisters" in James Joyce's Dubliners. In this story there are several characters that deserve attention:
(1) The narrator who was a friend of the Father Flynn, the priest who died--He had a close relationship with the priest, who had taught him many things about the church and the Catholic doctrine. Through the narrator we see a boy's reaction to death and to the adults who influence him--positively or negatively.
(2) Father Flynn--the priest who dies when the story begins. He is as the sisters proclaim a "conflicted" man. It seems that the role of the priest never truly suited him, and he longed for escape. His dream of taking a ride back to his childhood home represents his need to escape the confining role of priesthood. Flynn's decline begins when he drops the chalice and begins laughing uncontrollably in the confessional.
(3) The sisters--Much of what we know of Father Flynn comes from the sisters. The sisters are caught in the daily routine of caring for Father Flynn, but they worry about his aberrations. Their worry, however, does not cause them to act. When he dies, they proclaim that he is a "beautiful corpse." They seem to turn away from major issues and seek comfort in the daily routines of life.
(4) Old Cotter- Old Cotter is the first adult to cast doubt on the narrator's relationship with the priest, proclaiming that the boy should be out playing with boys his own age. At first the narrator resents Old Cotter, but later puzzles over his words.
