Does it have something to do with when the Mormons were in New York?
No, Hudson was founded by Quakers from Nantucket. It started out as a whaling port, and the alley in back of my house is named Rope Alley, because they manufactured long ropes along the alley for ship rigging. Brigham Young as a kid lived in nearby Durham for awhile across the river, before his family moved farther west to central New York. Supposedly Brigham Young when he was a carpenter still doing business with gentiles, built the fireplace hearth for William Seward in his home in Auburn, New York.
Gillenbrand lived in next door Greenport on Mr. Merino, which is where much of the bourgeoise of the area lives, enjoying magnificent views of the Hudson River from their hillside homes.
