I have not made any headway on finding definite proof on who the parents of my 4th great grandmother - Heloise Dubreuil- are (Dubreuil-2). She married Felix LaGroue (LaGroue-21) in 1843 in St Louis, Missouri. They are next found on the 1850 census in New Orleans, LA. I have found their marriage written in the corner of the St Louis Old Cathedral church record book, but it does not give any information other than their names. The wikitree page for Heloise assigns parents to her, but I cannot find any proof of this. Who is looking for a challenge? :-) Help would be much appreciated!
