This is William Henry Moorhead of Pembina. He was known to be, among other things, a land speculator and an undertaker. Why the text says he died in 1871, I cannot explain, but according to all sources, he did not die until 1897.
Sometimes referred to as "Highwater Bill" - according to the Chuck Walker's family oral history, because "...during one of the floods a wager was made between some men...Bill Moorhead drove a board in the water with a knot hole and said, 'The water will come up and run through the hole.' He won and later it was said that he came back after dark and drove the board deeper..."
Oh, dear...well, gossip aside, I rather like his moniker however he came by it, cheating or legitimate!
William Henry married Lizzie La Verea, a French Canadian, of North Dakota, where he was employed by the Hudson Bay Company, later owning a large tract of land and an undertaking establishment at Pembina, N. Dak.; the town of Moorhead, was named for him. He died July 3, 1897. His children were: James, Stanley, Shepley, Mary, Delia, and one or two who died in infancy.

Moorhead was one of the early settlers of Pembina, N.D., who had traveled in Roseau County before the white settlement. Two of his sons settled on what is known as the Northwest Angle of Lake of the Woods. Moorhead told J.W. Durham that Roseau County was the greatest. From Minnesota's Last Frontier
