Hi Nora, I have just come accross this site so I hope you get my message. I am fascinated to learn that there are Finucanes[Finukens] in Argentina. In Ireland we generally prnounce the name phonetically "fin-oo-can" but some [especially in England] do pronounce it as in your spanish spelling "fin-new-can". Norah [Honore] are common family names in my family [my grandmother was called Norah] My traceable family remained in Co. Kerry, Ireland although many did emigrate to the US. So I am sure that there is a connection.
