Hi,
I grew up near Copeland Rd and have always wondered if it's anything to do with my Copeland ancestors, but it looks more likely your folk from Ohio are who it's named for. Here's a death certificate I found for a Thomas Copeland living in California township where Copeland Rd is. He is from Ohio and so is his father.
