What is the meaning of the surname Finneral?

Answer 1

This surname doesn't appear in Griffiths Valuations in the mid-1800s.

It does appear in the 1901 Irish census: all 12 of them! There were 4 near Ennis, Co. Clare; 6 in Co. Kildare (Baronstown East); and 2 near Coolavin, Co. Sligo.

Ten years later there were only 4 in the whole country: at Ennistimon on the Clare coast.

It certainly is a rare surname. I suspect the Finn part of the name derives from the Irish fionn (fair) but that's all could conjecture.
