Hi Ian, If you skipped 194, it should be because they already exist on WikiTree. It appears that you figured it out since you asked the question.
In any case, you need to connect the profiles you have to their existing parents. Start on a profile you have that needs parents. Go to the edit tab. Scroll down until you see relationships. Click add/edit parent and follow the directions unless you already know the WikiTree ID for the person. Once you've selected the right individual, save your changes.
