I found a couple but it wasn't clear that they were duplicates as one was the father of Edmund and one was the son of an Edmund. There was no link in your message so I may have found the wrong ones. Can you no initiate merges yourself if you think they look like duplicates?
The manager of the ones I found was Serafina Liora
Here is the link to Thomas Stebbins. He has over 30 offspring and I suspect many of them are duplicates.
I am contacting you about this profile: Thomas Stebbins, Jr.
Please clean up what you can.
