I think they may have come via the northern access (at the time)through Canada but never came south of Wisconsin.
I also think it’s likely that a ship from India landed near where the original colonists landed and long before they did.
Might explain the unusual Indian tribes the colonists found on the east coast when they landed...but I am certainly no expert on this..just stuff I have read.
I remember back in 1990s when I was living in Fairbanks somebody discover Chinese artifact in Alaskan native villages they think that Chinese sailors were trading good with Alaskan natives
That is true story
