I hope I shall not be considered intrusive in communicating to you the Substance of the answer I have just received from M r Heckewelder to a Letter I wrote to him on the Subject of the Nottoway Indians. He thinks with me they are of the Iroquois, not of the Lenape family. He considers their name Nottaway , to be the Same with Nadowési or Naudowessie the denomination which the Chippeways (a...

Your polite & ready answer to the letter I had the honor of writing to you on the Subject of M r Vanuxem calls for the expression of my gratitude.

27Peter S. Du Ponceau to Thomas Jefferson, 12 September 1820 (Jefferson Papers)
The Vocabulary of the Nottoway language which you have had the goodness to send to me , has only encreased my thirst for more. There are, you Say, yet in Virginia remnants of the Mattaponey & Pamunkey Tribes—If vocabularies of those could be obtained, it might lead to interesting results.
