Harriet is probably the dau. of William and Abigail Howell as she and her dau. Francis are living with them in the 1850 Census.

It would appear that Nathaniel W. Fish had either died or left by 1850. I suspect that Nathaniel W. is the same as N. Winslow who died in 1842.

**this seems to be the same Amanda Clark that Charles Fish (proposed brother of Joseph Fish#2)was living with in 1850. In 1870, the household of Amanda & Erastus Clark included Buerell Howell, 19 and Isabell Howell 17 (Burnell, Isabell and Cynthia Howell appear in the 1860 census with Eliakim & Estell Howell. In the 1850 census Eliakim & Estella are living next door to William & Abigail Howell...Eliakim could be son of William Howell. In 1870, Eliakim is found remarried to Elizabeth, age 36, with dau Cemeline (Cornelia?) age 11 and Libbie age 1. Did Estella die and the older kids were shipped out to relatives?
