If a lot of trees are growing in an are where the barn stood I've gut my doubts about imported or shipped wood. Maybe for a wealthy persons home but not likely a barn as long as trees were close by.
In the hand hewn, mortise & tenon days, logs usually came from no further away that you'd want to drag one with a team of horses. Other than Chestnut, which is gone, look around the area where the barn stood & see what trees stand now.
These are the recommendations of some of the local historians when questions arise as to the construction of original log homes that dot the area.
