I think I have reached the same roadblock but from a different direction ... my however many great greats ... father was John Nutt, brother to Robert. John moved to Scotland I think in 1860, whilst others moved around the world: Andrew to Philadelphia, Margaret (?) to Invercargill NZD.
I have run into the Matthew Nutt dead end. Did you get any feedback on who, where, when Matthew lived, who his parents were etc?
