Searching for Isaacs wife, Esthers birth

1850 census shows born in VA. Is she Cornwell or Cornwall, that is my focus this afternoon:
Family Search: No results
FindAGrave: Searched Cass County Esther: Cragun, Craigen, Craigan, Cragan, = no results.
  Did Find via a search in Cass County a memorial for Caleb J Cragan, "the aged and well known citizen, died at his home at 722 Race street this morning at 9:30 o'clock, aged 73 years."

Isaac and Esther Cragun and Family and Spouses

The above is a photo off of Family Tree.Isaac is Patrick Craguns oldest son.

These are close descendants to Patrick Cragun. I am hoping that someone in Isaacs descendants, also then a descendant of Patrick might have a record confirming any detail of him. For example, Patricks Father is also a Caleb, we think. Can we confirm that? Who was Calebs wife? We have no details. I know it's a long shot, but there are 7 married children from Isaac. Maybe they will stumble along and be able to help.

Below are some of the fables or facts I would love to document:

• 
  The family of CRAGUN was founded in America by Patrick Cragun who came from Dublin, Ireland prior to the Revolutionary War and who took part in the struggles of the American Colonists that resulted in the winning of Independence. History of Cass County, Indiana p. 214
  Genealogical history of South West Virginia: Patrick Cragun had been arrested for the fourth time by the King's officers for his revolutionary tendencies.
  The identity of his wife, Rose Alley (or Abby) or Hanna Elsy (perhaps a second marriage) is unclear as is the date (1780's) and place of marriage. They are however, tied to Russell County, Virginia located in the extreme southwestern part of the state 20 miles north of Bristol, through the record of their eldest son Isaac as recorded in the Cass County history. Otherwise the family is more closely identified with Sullivan County, Tennessee which borders Virginia and shares the city of Bristol.

Isaac Craigen

This is a photo of the 1850 Census of Isaac Craigen Family. The 1820 Census spells it the same.

Data from this census: Esther not Esher
Both Isaac and Esther born in Virginia
Patrick age 23, Caleb age 21, Martha age 15, Esther age 13 confirms new family search data: all born in Indiana: Interestingly shows Caleb and Martha attending school that year.
