My grandfather Charles Savageau, whos family comes from Quebec area. My Great Uncle his a Priest in Canada and has done extensive searches and about to publish a book about the three (3) Savageau lines. Three brothers who went to Canada from France got in to some sort of a dispute and split up. Each changing the way they spelled there last name: Savageau, Sauvageau and Savageaux. There sons left to go the US to North Dakota, which has a huge line of Savageaus; Michigan, Wisconsin, Colorado, Vermont and California. Of course there are other lines in other states, but these seem to be the biggest. I found relatives in Las Vegas. I hope this helps some of you.
