Usually I try to find examples of both, but here I don't see Plumer until --
What is now Chandler Ln, east and south of here, used to be Plumer
TIGER 2017 shows both The Sound Of Music -- sorry, I mean Plummer here and Plumer there
*but* USGS Topo, while not naming this road here, shows a Plumer cemetery that's not present in OSM.
Under the trees, may be visible in ESRI Clarity.
Plumer is however the name of the road on the Topo map named northwest, where OSM has it changed as TIGER to Nottingham Square.
With that, Plummer, you are the weakest link, goodbye.
Not conclusive evidence though
