Alfred Brunson visited the Indians at La Pointe in the winter of 1842–3, on an embassy from the government, he selected young Warren, then seventeen years of age, as interpreter, and found him very ready and skillful. Hon. Henry M. Rice writes: "In the treaty of Fond du Lac, made by Gen. Isaac Verplank and myself in 1847, William was our interpreter. (See Statutes at Large.)
