Joan, you might want to add some tags to your post, like mentors, that will help get your post attention, but I will answer your question the best that I can. First of all, I noticed that you are registered as a guest member which gives you only limited rights on Wikitree. I would suggest that you look at the different types of Wikitree memberships under the drop down "Help" list at the "Intro to Wikitree" tab. If you become a full-fledged member, you will be able to do more with your profile and family tree.
Also, I tried to find your family tree on ancestry.com but I found nothing. Do you have an active account with ancestry? Did you withdraw your DNA from them? If you never opened an active account with them and created a family tree, I don't think anything will show up.
Third, what most of us who want to compare DNA do is upload our ancestors.com or other DNA test results to GEDmatch.com and use those results as a matching tool. Give us a little more information about what is going on and perhaps we can address your questions better.
