Thanks for verification. I am descended from Marguerite of this family. I have the youngest Edna, as listed born in IL. marguerite ended up living/marrying in IL (married Coulombe). Eventually Alexander and Edward and Edna and Emma all living and marrying in Chicago area, IL. It appears the rest of the family IS from Vermont. Burlington Chittenden area after all. I surmised this as all the census records w/ the surname are from there.

Do you have further any info on Louis Deyette's ancestry?

Thanks for the correct spelling of Courville, I have it as Curvill. I have absolutely nothing on that line yet.
