Finnish ancestry in the Forest of Dean? (General)

Hello
This is my first posting on here.
I am not from the Forest of Dean, but my grandfather was. In fact his entire family going back many generations were.
Recently my sister had a DNA test done and we found we have Finnish ancestry. It seems, from physical appearance,that it probably comes through my grandfather's line.
So I'm wondering whether-
a) anyone else has found they have Finnish ancestry?
b) has any research been done to show this?
c) are there any records with Finnish names on them?
Family names I've made extensive researches into are-
Morgan
Trigg
Sier/Seier
inc Sier Trigg
Burcher
Tingle
and more I can't remember!
Any help would be gratefully received.
Thank you
