RootsTech 2022 comes with a useful tool called Relatives at RootsTech. You will have to create a family tree at FamilySearch.org or upload a GEDCOM-fil. If you already have a tree, it could easily be extended from a GEDCOM file, so it goes past the year 1800. The article How do I copy information from my GEDCOM file into Family Tree? gives instructions on how to do so.
Make sure you are signed up for RootsTech and choose Menu and Relatives at RootsTech. View your relatives. Click into each of them, and you could choose between Message, Relationship, and Contact. Under Relationship, you will find a tree that shows your connection to the other person.
If you compare this to your DNA results, you might have some new answers today! Happy hunting!
