The problem with the country when it started out, was that the old colonial charters drew borders that were incredibly ambiguous and conflicted. Throw in the fact that many colonies were “cross-pollinated” by people from other colonies. Long Island was colonized by people from Connecticut. You can still find old New England congregationalist churches on the east coast of some deep southern states. This was the genesis of the land war between PA and Connecticut during the Revolution. Everyone thought they had a claim on the land of everyone else.
Yes, knew about the (surprising) conflicting claims of Pennsylvania and Connecticutians, based on terms of royal grants IIRC. Also learned about how pre-statehood Vermonters fended off surveyors and land claimants from both NY and NH, eventually becoming the 14th state after those pesky NYers and NHer got tired of getting violently jumped and shot at.
