Thanks you for that information. That clears some things up.
In that case, is there any simple way for me to find a record for this Jean Nicolas Gross that was supposedly born on 19 Oct 1819 in Herbitzheim? He obviously wasn't born there because there is no civil record for him, although there are Grosses in this town. His supposed parents are Jean Nicolas Gross and Maria Madeleine Biebel. This was information from a Find a Grave entry, so who knows how accurate it is. I messaged the person who created it to find out where they got the information.
If he wasn't born in Herbitzheim, I'm assuming there will be no easy way to find it other than trying to find out exactly where he was born.
