Well, since we are adding names that don't have to be doctor names, I'll add these two.
When I was a firearm salesman 10 years ago, I had a regular customer named Harry Dick. His middle name was Dwight, and yes, he handed out business cards that had his name on it, Harry D. Dick.
An old childhood friend of mine had a dad that went to financial planner named Wayne Dwop. My friend's dad told a story about how the school kids started singing,"Wayne Dwops keep falling on my head," when the movie Butch Cassidy, and the Sundance Kid came out when Wayne was in school.
A girl that lived down the street from me when I was a kid was named Candy Gum.
