Call me a dork, but I always find stories like this terribly interesting.
cool! i’m sending this to my artist friends! :) they’ll love it too. thanks for sharing BattleHymn!
A very quick search tells me “Janetta” was perhaps a common name back then.
“....James Voorhees was placed on the pension rolls as a Sargeant in the US Infantry on 17. Sep. ...... Janetta Voorhees was born in 1856 at New Jersey. ...”
Voorhees was someone important (Voorhees High School, etc.). Perhaps the falls was named by the painter in honor of someone important.
Although I would like to think that perhaps the artist on a romantic walk in the woods with a young lass promised to name the falls in the painting after her if....
