Hi Nathalie,
Welcome to WikiTree. You can review the current WikiTree Privacy Policy here.
Hi Jeannette, We are so glad you joined us, but there is a bit of a learning curve to WikiTree. I looked at your 55 contributions and saw two gedcom files that were submitted for matching. I am not sure if the process was completed, but both files have been deleted. Eowyn will probably be able to help with this.
WikiTree is a one big worldwide family tree. We each donate a gift of our research on our branches, twigs and leaves to the same big family tree. The goal is for each person in the world to have one leaf, called a profile, on the WikiTree. If there are two profiles for the same person, they need to be merged back down to the original profile. One profile per person, and we all share the information on that profile by contributing better information and better sources to improve the profile.
I see that your own family twig has you, your parents and your grandparents. At this time, you have not connected your twig to your family WikiTree branches, so you are currently cut off from the main tree trunk. Your DNA tests should show up on your paternal grandparents tomorrow, after the nightly database indexing. Each night the database is indexed and that is when notations such as your DNA test are applied to new profiles. It should be there tomorrow.
I hope this answers some of your questions. I doubt that anyone is questioning your research. More accurately, we are looking for duplicate profiles that need to be merged back down to the first, original profile for each person. I feel confident that your research will go a long way toward improving the profiles of your family branches on the WikiTree.
