The problem with knowing what was COMMON with Eastern Indian cultures prior to 1800 or so is that there were no organized museums until the 19th century. What pieces exist come from private collections, and family records are not always Accurate on the date of the article. Some of the best sources of early information are found not here in the USA, but in England, and France, Believe it or not. Even the Dutch museums have articles saved from the early occupation of what is now New York.
Years ago, when I was trying to make up a local "Persona", I made a trip to the Field Museum of Natural History in Chicago, trying to find out what the Indians wore- cloth type, beads, shells, etc.-- particularly for the Potowatami, Sauk, and Kickapoo tribes which we know were living part-time in the central area of Illinois. A curator sent me to a Second floor galley, where there is a display of "Plains Indians" clothing, that includes some garb worn by Potowatami Indians. However, on viewing the display, The loin clothe, and shirt was made of gold fleur d lis on a royal blue background, clearly influenced by the French flag. That put the "clothing" displayed as AFTER Europeans had engaged these Indians in substantial TRADE, giving them the cloth to use to make these clothes.
I went back to the curator- behind those huge, Closed doors marked" Staff only" and asked him about earlier- pre-french garb, and he admitted the museum had NOTHING from those early Dates. Remember that it was the French who first Explored the " Illinois Country"- not the British.
Several friends interested in the French and Indian wars, clothing for their personae, have made the trip East to several museums and restored forts, looking for information. They have receive the same "news" from the curators of those sites- no one was collecting anything back then, as there was NO value placed by early settlers on preserving these "Heathen " cultures.
Sorry. :idunno: :hatsoff:
