In September of 1820 Colin was sent to the Sisseton near the Blue Earth River to bring in the murders of two of Manuel Lisa's men. He brought back to recently built Fort Snelling a Sisseton War Chief who claimed responsibility for the deaths. In 1821 & 1823 Colin was interpreting at councils held by Taliaferro at Ft.Snelling between the Dakota & visiting Ojibwe. By 1855 he is near the mouth of the Platte River.

Scott Campbell: (1790's-1851)
     He was the son of Archibald John Campbell & a Dakota woman and married Margaret Menager. Their children were: Henriette S. (b.1824; m.Benjamin Aitken Dyomme), Scott II (b.abt.1828-1870), Hypolite S.(b.abt.1828),  Joseph S.(b.1827/36-1869; m.Mary Ann), John S.

     As a boy, Scott was taken back east by Meriwether Lewis (of the Lewis & Clark expedition) on his return from his western journey. When Lewis died in 1809 under mysterious circumstances he returned to family in the Upper Mississippi. He was licensed to trade above Prairie du Chien for James Lockwood in the 1819-20 season. In 1834 he was Indian agent Taliaferro's Dakota interpreter at Fort Snelling, where he assisted Lt.Edmund A.Ogden in setting the Dakota language on paper. Missionary, Samuel W.Pond credits Scott for his part in the manuscript that Ogden passed on to Samuel & his brother Gideon Pond which was helpful in their work in developing a Dakota dictionary that was finished & published though the efforts of fellow missionary, Stephen R. Riggs. In 1837, Scott was living at the St.Peters settlement, near the mouth of the Minnesota River, going to Washington D.C. as the Dakota interpreter for a treaty. In 1843 he bought a claim from Denis Cherrier for $300. which he sold to William Hartshorn in 1848. Pond wrote of Scott, "Mr.Campbell was, in his general deportment, very mild, quiet and gentlemanly, always ready to smoke or chat with white men or Indians, carefully avoiding all harsh language and disagreeable topics; but he had a fiery temper which sometimes broke through the smooth external covering in such ebullitions of passion as we might expect from one in whom were mingled the Scotch and Dakota blood. He was skillful as an interpreter, and perhaps more skillful as a mis-interpreter...He told what he thought the speaker should have said rather that what he did say, and frequently a good understanding seemed to have been restored, simply because there had been no understanding at all."
