The profile is not project protected and you are pre-1700 certified so you should feel free to add primary source documentation to the profile.
Please see my comments regarding Ancestry trees on your other question of today for a longer comment. In pre-1700 profiles we should not use Ancestry trees (or Geni, etc) as sources because they are not. If they have underlying primary source documentation, use that underlying primary source as your documentation rather than the tree.
