In the 1850 census she had property = $2200. Left by her first husband?
1860 Scott Co, IL. At age 59 she was a widow and head of the household which included: Daniel, 20, Elizabeth, 13, and John H, 11. Sarah's occupation was farming and her property totaled $6000/490. Apparently the children had also inherited some personal property as Daniel had $400 worth while Elizabeth and John both had $300.
7/22/1870 Same place. That year the census said Sarah was 68 and was a housekeeper but still head of the house. Her property had grown to $9600/800 but probably had turned over the hard farm work to son John, 21. Daughter Elizabeth, 22, was still at home as well.
6/2/1880 Still there, near Exeter. Sarah was then 78 years old but living alone. Next door was the family of son John and next to him was Daniel's family.
Daughter Sarah told the 1880 census taker that her mother was born in OH.
