Summer, You may find this interesting...
The ability to confirm with DNA is all or nothing.
Parent-child relationships can be labeled Confirmed with DNA when there is a sufficient amount of shared autosomal DNA between two relatives who are third cousins and closer. It is necessary to use triangulated groups — three or more matches on the same DNA segment — when the testers are greater than third cousins.
A sufficient amount of auDNA is determined by the total number of cMs of several segments normally shared specific relatives. See Mathematical Average for auDNA Sharing andAre There Any Absolutes in Genetic Genealogy?" see help.
You only care about the amount of shared autosomal DNA between two relatives who are third cousins or closer. You and Jeanne are not third cousins or closer. The guidelines for you and Jeanne are...
"If all the test-takers have uploaded to GEDmatch, use their Triangulation utility or One-to-Many utility (for you and each segment sharing cousin). Find segments measuring 7 cM or more that you share (i.e. overlap) with two or more distant cousins.
Those who all match each other on the same segment form a triangulated group (TG). Using WikiTree's Relationship Finder find the shared ancestral couple for that TG." see help
There are a few interesting things to point out. The requirements only care about triangulated groups which 3 distant cousins share a single 7cM or greater segment. You don't need to predict the relationship between you and Jeanne.
1. This means that you only have to find one additional distant cousin who shares a single 7cM triangulated segment, to mark all the profiles up to and including the 2 shared ancestral couple. This is ok when you don't have a paper trail and are looking for clues as to how you are related, but it certainly falls short of proving an existing relationship.
2. You may be a 3rd cousin 1x removed but these rules allow for you to mark all profiles, even if the prediction is distant, based on a single 7cM triangulated.
3. There is no requirement that the additional match needs to be more distant, which means that you are proving pretty much nothing.
4. The x chromosome is obviously wrong, but even if it were corrected. You could Confirm with DNA any match, including a 3rd cousin 1x removed, with a 1cM match on the X Chromosome, even if the prediction is NO RELATION.
