The Stelly/Gautreaux Family of Louisiana

All names are due to spelling errors depending on sources.Trying to fill in information on both the Stelly and Gautreaux family trees. Any information would be greatly appreaciated. I know there is at least one family tree which traces roughly the same ancestors. I'm brand new, so please have patience! Also, I am having trouble finding info on my grandfather Henry Gautreaux, married to Laura Butaud in Abbeville, Louisiana.
