FINCH
As described in historical dictionaries
Patronymica Britannica (1860)
FINCH. Perhaps a corruption of Vincent. Vincent Herbert of Winchelsea, 20 Edw. I. bore the alias of Finch. The early pedigree of the Earl of Winchelsea's family is very obscure. Their former surname was Herbert, and one of the earliest if not the first who was knovn as Finch was this very Vincent. In support of this notion I may add, from Collins, that the family had previously borne their father's name, as Herbertus filius Herberti, &c. In the H.E. the spelling is Fynch ; in 13 Edw. III., Vyuche. In Sussex the baptismal name Vincent is often corrupted to Winch or Vinch.
