Gary, if you click on the "edit" tab, and look on the right-hand side of the edit page, under the bold heading "Edit Family," you'll see a line for "Children:". There's currently a private daughter in that slot. Click on the "add/edit" link under the daughter, and it'll open a new tab for editing the children. Pick the second option ("II. Remove") and it'll take you to the bottom of the page, where you click on "Remove Child From Prior Pavy." It won't remove her profile, so don't worry about that; it'll just disconnect her *as his child.*
Once you've got the wrong child out from his profile, you can follow the same steps to add the correct child (your grandparent, I presume), only selecting the first option instead of the second. If they already have a WikiTree profile, just enter their Wiki ID number in the box at the top of that same edit page.
That should get everybody hooked up correctly. If this doesn't solve the issue, or is unclear, please post back here. Good luck!
