Possibly derived from Greek πηνελοψ (penelops), a type of duck. Alternatively it could be from πηνη (pene) "threads, weft" and ωψ (ops) "face, eye". In Homer's epic the 'Odyssey' this is the name of the wife of Odysseus, forced to fend off suitors while her husband is away fighting at Troy. It has occasionally been used as an English given name since the 16th century.
