He was a railroad magnate in the era of EH Harriman, rail tycoon, associate of the Walker-Bush tribe.
Thus the Bushes & Hinckleys seem to have known each other for some time.
Many more strange & wondrous things to be found from tracing these connections, such as the familial ties between the Mormon founders & the Bushes & Hinckleys.
