Harriett Bowles was the youngest child of John and Celia (Sally) Bowles. She was born in Kentucky, almost certainly in Barren County, about 1841, according to the 1850 census. No other references to her have been located. Specifically, she does not appear with her father in the 1860 Metcalfe Co KY census. Since she would have been about 19 at the time, I scanned the entire Metcalfe County census book for a Harriett about that age who might have been her. No one was found named Harriett within the age range of 18-20.
Two reasonable possibilities suggest themselves: (1) Harriett died before 1960; or (2) she married someone who lived outside the area included in Metcalfe County when it was created in 1860.
