I am a descendent of Joseph Fondal and Marie Louise Fondal. Joseph and Marie Louise Fondal were my great-great-great-great-great-grandparents through their daughter, Felicite who married Adolphe Rochon. I am researching our family lineage and would be very happy if you could share any information you have.
I would like to say, that I see some errors in your original post. As I already mentioned, Marie Louise Fondal was the spouse of Joseph Fondal, and her maiden name was Mathieu. I have the census records to prove these relationships saved in my family tree, which I welcome you all to have a look at.
