Which brother does Antigone bury against King Creon’s will in Sophocles’ Antigone (441 B.C.)?

Antigone’s two brothers are Eteocles and Polyneices.

Both are dead when the play opens, but Creon forbids the burial of Polyneices, who had rebelled against Creon’s rule.

Antigone gives him a token burial anyway. Antigone also has a sister, Ismene.
