When the George Weston mansion in Plainfield burned a few years back, it raised the question -- who was George Weston?
He built the mansion in 1929, but as I recall from previous research (which I apparently didn't blog), he had relatives in and visited Plainfield well before then.
He made his money as a mid-level popular author of his day.
I found this novel of his: You Never Saw Such A Girl which is largely centered around "East Mountain" which seems to be a fictionalized version of Ekonk Hill. The nearest main town is Plainfield, with mentions of Jewett City and as I recall other local towns. There is also an about three day journey by camper-truck (in 1919!) to Newport.
