Perse or Persei's was the daughter of Oceanus and Tethys, and the mother of Perses by Helios. To judge by the next three names, including the famous Persephone and Perseus, Perse's name ought to mean 'destruction', from pertho, 'to destroy'.

But we are given no reason for preferring this meaning, and perhaps it is best to say that she simply acquired the name from her son. The only other thing we can do is to link her name somehow with phero, 'to bear', 'bring', 'produce', 'gain'.
