According to the "History of Ionia and Montcalm Counties, Michigan by John S Schenck):
“When Nathaniel was but twelve years old his father died, and he lived with his mother until he was sixteen, attending school a portion of the time and earning small amounts, between his eight and sixteenth years, by cupping water at the famed “Congress Spring.” He assisted in clearing up the land which is now the park, and after the death of his mother, which occurred when he was sixteen years of age, he found employment by the month on a farm. Two years afterwards he went to Niagara Co., N.Y., and continued farm-labor for hire for five years. He was then married to Louisa C. Martin, a native of Whitby, Ontario, Dominion of Canada, where she was born Dec. 22, 1813.” [Congress Spring is in Saratoga Springs NY].
