I justified the upgrade as a Christmas present to myself!

And I guess it's a similar situation for the North American match - confirmed line back to a man born in North America around 1810s. Father's name not recorded anywhere they could find, and on a census the son had said his father was born in Ireland.
With the other match there wasn't any particular burning question. Turns out some of the Y37 GD=0's relatives are autosomal matches to some family members. Not many, and it was sheer luck that some people were at Gedmatch where it is easier to work with the info. This family had thought their earliest known ancestor had a Scottish forebear, but he must have been from the West Country.
