Quatrevingt Family Genealogy Forum
An interesting note to add to the discussion. A few years ago when I was researching the Quatrevingt - Achtziger family at the Courthouse in Edgard, St John the Baptist Parish, Louisiana, I found succession (probate) indexes from the mid 1800s using the numerals 8 & 0 to identify the family. In lieu of a surname, "80" was used. I suppose this made some sense as most everyone in St John Parish must have spoken French at that time and "80" was a good abbreviation for Quatrevingt.
