A land deed in Chesterfield County, South Carolina1 states that Sarah Christian and Susannah Wadsworth were the daughters of John H. Wadsworth deceased.
John H. Wadsworth, b. 1793 married Susannah Davis, daughter of Thomas & Nancy Davis about 1819-1820. John and Susannah had two children, a son, Lewis H. and daughter, Mary E. Wadsworth. Sarah Davis Wadsworth died sometime between 1870 and 1880.
In the 1880 Census2 we find John H. Wadsworth, age 81, remarried to a lady named Mary LNU, age 28, with a newborn daughter, Sarah C. Wadsworth, age 8 months.
1880 CENSUS: Cole Hill, Chesterfield County, South Carolina; NA Film Number T9-1225; Family History Film: 1255225; Enumeration District: 004; Page 307A Line 25, Dwelling 107, Family 107; Jno. H. WADSWORTH, male, age 81, Farmer, born in SC, parents born in SC; Mary WADSWORTH, Wife, age 28, born in SC, parents born in SC; Sarah C. WADSWORTH, Daughter, age 8m, born in SC and William CRASS, male, age 9, born in SC.
We know from the 1880 Census that his wife Mary and a daughter Sarah C. most likely survived him. The Chesterfield County Land – Alexander Martin to Sarah C. Wadsworth and Susannah Wadsworth dated 24 January 1886 clearly show that in 1886 a second daughter, named Susannah, was born after the 1880 Census enumeration.
So in January 1886 we know that:
John H, Wadsworth is deceased. (Died between 13 June 1880 (1880 Census) – 24 January 1886(Land Deed 8:536)
His wife Mary, as a young widow, is presumed to be alive though there is no mention of her.
Daughters, Sarah Christian and Susannah Wadsworth are living.
Then in the 1900 census3 we have this listing for the Lewis H. Wadsworth, the son from John’s first marriage to Susannah Davis.
1900 CENSUS: Cole Hill, Chesterfield County, South Carolina; Roll: 1523; Enumeration District: 19; FHL Microfilm: 1241523; Page 3A, Line 29, Dwelling 49; Family 49; Lewis H.

WADSWORTH, Half-Sister, age 20, born Nov 1880 in SC and Carrie T. CHANLDER, female, Servant, age 31, born Oct 1869 in SC.
At this point we find no information on either Mary, the wife of John H., or Susannah Wadsworth, their daughter. The older daughter, Sarah C. Wadsworth is documented in the household of her half-brother Lewis H,. Wadsworth.
After 1900, no further information had been found on Mary (LNU) Wadsworth, Sarah Christian Wadsworth or Susannah Wadsworth. At present, no additional information is know about these three women.
