"Our community's mission is to grow an accurate single family tree that connects us all and is freely available to us all."
Point I of our Honor Code is:
"We collaborate. When we share ancestors we work together on the same ancestor profiles."
Francis Garrett Yarborough-324 is an "Open" profile. If you have a reliable source that Francis is the son of Richard and Anna, your great-grandparents, you can feel free to add that source and edit Francis's family adding his parents.
Communication with an active manager of a profile to discuss some changes or editions to the profile is very important as adequately Lindy says.
The only contributions of the manager were on 16 Sep 2016.
You can go on with the "Unresponsive Profile Manager" procedure to have the profile orphaned so you can adopt Francis's profile later.
Hope you find helpful this information.
