Hi Anne. It looks like you're the Profile Manager, so if you're sure it's a different person, can't you just remove the incorrect obit? And perhaps substitute a valid obit if you have one?
You might also consider adding a Research Note to the profile explaining that there's another person with the same name, so somebody doesn't come along later and repeat the mistake.
And if you're concerned about upsetting another member who was trying to help, you can always send him/her a nice note explaining the mistake.
