The Treadwell family possessed a charter from Charles II and originally settled in North Carolina. Some members of the family moved to the Mississippi Territory when it was still considered the Choctaw Nation. They settled in northeastern Mississippi around Lamar and Davis Mills (now Michigan City), where some family members remain today. Allie Treadwell married J. Marvin Aldrich, uniting the two families. Materials created by both families exist in the digital collection, though the overwhelming majority represents the Treadwell family.

Digitized items include family and business-related correspondence; business documents, including receipts for cotton and other goods, ledgers, estate inventories, and more.

This digital collection contains the first six boxes of a larger collection, which is described in detail in an online finding aid.
