Ok, you want to have the biological parents listed for Dewitt. Your saying that Jonathan is correct but you want to change who the mother is.
On the edit tab, of Dewitt, on the right is the edit link for his parents, you can removed his mother using this feature. You can also use these edit links to adjust the marriage dates as well.
It would be wise to document your reasons why in the bio.
Let me know if you need futher help. Since you are the profile manager you should have no problems making the change. Otherwise you would need to discuss this with others including those on the Trusted list under the Privacy Tab.
Include your reasoning any and source info you can cite.
Let us know if you need further help as these profiles are open, we can easily come in and make the changes for you but it is best if you learn how.
Thanks for bringing your question to the G2G forum
