Fenton was
clerk of court for Crawford County when he was chosen as the delegate to the
Wisconsin Territory's Second Constitutional Convention from Chippewa and Crawford Counties, replacing
Peter A. R. Brace. At the convention, he advocated a western boundary for Wisconsin deep into the
Minnesota country, running from the
rapids of the
St. Louis River above
Duluth-
Superior southwest to the juncture of the
Rum River with the
Mississippi, and thence to the Illinois line. (This wedge of additional territory included the sites of
St. Paul and
Stillwater, and indeed the entire
St. Croix Valley.) This motion passed in the Convention by a 53–3 margin, but was eventually rejected by Congress in favor of the present boundary line. The most extensive analysis of this effort points out surviving letters demonstrating that Fenton was an ally of
Hercules Dousman and hoped that the advocates for a
Minnesota Territory would push for cession of
Dakota Indian lands, thus providing the Dakota with money to pay debts owed to Dousman. Fenton later was elected as county judge in Crawford County, and held that office at the time of his death on August 11, 1851, in Prairie du Chien, "aged 39 year and 7 months". He is referred to in the headline of the announcement as "Col. DANIEL G. FENTON". His wife Madeline is reported to have left Prairie du Chien, and possibly Wisconsin, soon after his death. == Identity question ==
