24th prince of Dol Amroth, 2nd in the Fourth Age (PM/221, 223). The language and meaning of this name are not clear, but unlike the names of earlier princes, this name appears to be Sindarin instead of Adûnaic. His name seems to a compound of alph “swan” and ross¹ “foam”, hence: “*Swan Foam” (as suggested by David Salo, GS/340).
