This was pretty exciting for me to discover. It’s pretty obvious to any homebuilder that different cultures have different ways of building homes. In Maryland, the predominant inland culture is reported to have been longhouses (like the Onondaga in New York) and agricultural.
Longhouses were also used by the Vikings in a manner similar to native american culture. Were they an import from the early Viking culture? Longhouses used by Native Americans are present on both the Pacific and Atlantic coasts of North America in 2 predominant forms. Archeological evidence among the Iroquois in upstate New York indicates they were built on the east coast as far back as 1100 AD. This is somewhat later than the proposed Vinland excavation longhouses in Labrador dating to 1000 CE, attributed to Erikson. These presumably were turf/sod like the Iceland and Greenland variants, rather than wood like the Norwegian/Danish variants.
The word for Iroquois is Haudenosaunee. The first syllable is pronounced hod like the old Norse word for house “hus” but a little different. If I had to guess on the second part, I would say sohn or son, but it is pronounced “shon” The first part of the word out of context might be Germanic, the insinuation from the linked site above, I might construct “sea hut from ship of the north sea” out of the word, Hud-der-Nord-See with an n on the end to indicate plural as in tribe, and with an ee on the end to indicate “a person deriving from this”, the same ending found in Cherokee, Shawnee, Hopi???.I guess the above analysis (probably incorrect, but interesting) might suggest the Haudenosaunee word is an exonym. The Dutch were in the area pretty extensively, and Dutch is a Germanic language so it might derive from a Dutch label. It would be very hard to determine if the name predates Dutch culture.
