I just wanted to share a bit of fun research I did. Maya and I were researching eponymous nymphs with heroic husbands that became their community’s found father. To that end I I checked all the placenames in the catalogue of ships and the names of all the Oceanides. I came up with a list of 15 such pairings, thanks to http://www.theoi.com See list at http://www.shortstories-bill.blogspot.com/2015/01/eponymous-nymphs-and-heroic-husbands.html
The whole time I am looking up name after name, I keep thinking about the story of the shepherd Rhoecus who rescued and wed a hamadryad. The earliest reference I could find for the story was a poem by James Russell Lowell (1873) under the name "Rhoecus" . It finally occurred to me to use N-gram; https://books.google.com/ngrams/ Years ago, Google scanned millions of books; you can track word usage over time in their collections by using the website. N-gram made it clear that Lowell was the source of the stories fame, but also included evidence that the story was around and the name of Rhoecus long before.
So then I googled “Rhoecus” with various dates previous to 1873 until I stumbled upon “Bell’s Neo Pantheon” (1790) which offered the alternative spelling of “Rhaecus”. The name was written in that old style with the “a” and “e” stuck together, which Sarah told me is called an “ash”.) Anyway, Bell’s reference for the story is the Scholiast of Apollonius Rhodius II 471, quoting Charon of Lampsacus.
I just thought all this sleuthing was cool, so I had to share!
