The Pennsylvania Dutch are actually Deutsch, and it was recorded wrong at Ellis Island, or so the story goes. Jack Sobon calls Dutch barns "Lowland European" barns.one of the New York Dutch barns I restored had German carpenter's marks, and was built for a Jacob Duesler (sp).

Any Dutch barn I have been in, or have seen photos of, has had both pins, and wedges. Also, they have been predominantly white pine, with oak (red and white) braces and door posts. Pitch pine, a hard Southern pine, was common in NY, and I'm told oak was fairly common in Northern New Jersey. Can you imagine raising an oak H bent with gin poles?
