|(Philadelphia) Times - August 16, 1891|
The 1881 and 1893 maps both label the mill as "A. Derrickson", presumably for Aquila. This is slightly problematic in that Aquila Derickson passed away in November 1881. The Joseph mentioned in the article was Aquila's eldest son, who it seems acquired the mill after his father's death. I think the 1893 mapmakers may have leaned heavily on the 1881 version, since I recall seeing other instances where the later map seemed like it was not updated.

I'm still hopeful that someday I'll stumble upon...um, I mean gallantly discover, more about this mill. If nothing else this article gives us an idea of the state of the mill in the early 1890's. My hunch is that it had already been shut down for good and was never rebuilt. If more comes up, I'll be sure to pass it along.
