Jeanne; My grandmother's maiden name was LaRonge and whe was born on the Lac Courtre Oreilles Resv.(Chippewa)in Sawyer Co.WI. Her grandfather came from Lac LaRonge, Seskatchewan,CA and we're almost positive hetook that name for his own (LaRonge) as was the custom. It's called a 'dit' name and is the equivalent of our (English) 'alias'. I've come accross the name 'Larouque' and LaRoche or LaRush while searching for the names LaRonge and Lozon. However, they are all different names and lines. Although, all four of these names, LARONGE, LAROQUE, LOZON, AND LAROCHE seem to be related both distantly and/or by marriage. There is a lady by the name of Lois at the Native American forum who's reasearching the same name as you. If you haven't already, you might want to contact her. Hope this helps.
