I have been through that archive of records before. There are places which are not indexed there such as Graumont. I've also been through several of the area 10 Year Tables for births 1820-1840 myself one week out in Salt Lake. I found some possibilities and I remember that one now that I have reviewed my records. It's just that they really don't match up and I cannot find an Aubry/Sallot marriage. So, I'm still holding out.
