We have learned that the elderly lady who was looked after by Herbert and Hattie Stetson was the older half-sister of Hattie's mother. She had been born in 1800 as Ruth Putnam Haskell but was known now as Ruth P. Brooks. But we didn't know who Brooks was or the circumstances of her remarriage. 

Martha Haskell was Harriet Smith's mother, thus Isetta's grandmother. It is wonderful to find this photograph of her on a Find-a-Grave page, along with a headstone image and data about her burial. 

She died at age 50 in 1872. She is buried with other Haskell family members at Brownwood Cemetery in North Bloomfield, Trumbull County, Ohio. 

Here is a biography of Thomas Nelson Haskell from Find-a-Grave. 

The most famous of the 15 children of Captain George Henry Haskell was the second youngest, Thomas Nelson Haskell, who among other accomplishments was a founder of Colorado College. 

In that college's Tutt Library Special Collections are his collected papers.
