In "Eveline," how does Eveline's mother's death relate to her decision not to go with Frank; why did Eveline refuse to go?

The
night before the ship's departure for Buenos Ayres,experiences and recalls several events that
help her determine to go with Frank to Buenos Ayres. She hears a sreet organ grinding and is
reminded of her promise to her mother to keep the family together as long as she could. She
recalls the last night of her mother's life, in which it closed in "final craziness."
Finally, she recalls her mother's voice "saying constantly with foolish insistence:
"Derevaun Seraun! Derevaun Seraun!"" This is seemingly a nonsense
"foolish" statement, whether of a Gaelicor only gibberish.

The
recollections Eveline has that are associated with her mother's death sway her one way and then
the other: she doesn't want to continue in a life of abuse; she owes a duty to fulfill her
mother's last wish; she doesn't want a life that ends unhappily in "final craziness";
she wants to fulfill her promise to "keep the family together." Finally, it is the
recollection of her mother's "foolish" repetition of a seemingly nonsensical phrase
that triggers Eveline's independent resolve and determines her on seeking a life of freedom with
Frank.

At the dock, when she and Frank are awaiting time to embark, her fears
and confusions--the same ones that vacillated through her mind and heart the night before--rage
around her as fiercely as the sea to which Joyce symbolically links them. Her duty to her mother
and father and religion and moral purity are all subsumed in her prayer to be shown her duty, a
desire undoubtedly heightened by her death-bed promise to her mother.
