After Lysimachus' death in 281 BC, Arsinoe was briefly married to her half-brother Ptolemy Ceraunus from 280 to 279 BC and then to her full-blooded, younger brother Ptolemy II of Egypt from the late 270s BC until her death. Ptolemy II's children by his first wife [[Arsinoe I]], including his eventual successor [[Ptolemy III]], were posthumously declared to be children of Arsinoe II in the late 260s BC.
