Vermont is the state in which I have the fewest colonial ancestors. That may be because many New York and Connecticut families migrated into Vermont. I have no New York families and my Connecticut ancestors didn’t go to Vermont, they went to Canada when the American Revolution ended!
However, if you have Vermonters in your family tree, there are a number of great resources.
My state genealogy resources series pretty much has a focus on free websites, but for New England states, I have to make an exception and mention the New England Historic Genealogical Society in Boston and its website AmericanAncestors. Anyone with serious New England roots should consider joining NEHGS.
