From an 1891 edition of the Detroit Free Press:

“A singular freak of nature has manifested itself at Saratoga. Mrs. Francis originally had very black eyes and a beautiful head of very black hair. She is about 70 years old now, in good health and a rich widow. When she was about 50 her hair began to turn white, and in a few years the whole of it was as white as snow, and so remained until about a year ago, when it began to turn black again, and has now, without the use of any artifical means and purely as a freak of nature, almost wholly returned to its original color, and is as long and silky as when she was a young woman.”
