I have no proof that Elizabeth is their daughter, but the only other SAMPSON in the county at the time was Valentine, and she is of an age to be his sister.
3.  Elizabeth SAMPSON, b. 1800-1810; m. 25 Sep 1828, Lawrence Co., OH, David CORBIN

1.  Jordan R. Dodd, ed.  1993.  Virginia Marriages:  Early to 1850.  Liahona Research, Orem, UT (Broderbund CD-229):

Sampson, Thomas	Powell, Winny	28 Jul 1791	Orange Co.
Clark, John	Powell, Winney	5 Nov 1794	Orange Co.

Numerous secondary sources are lumping these two Winifred POWELLs together, but note that the second Winney married John CLARK as Winney POWELL, not as Winney SAMPSON.  Some secondary sources give the parents of the Winney POWELL who married John CLARK as John Stevens POWELL & Martha BURT, which jibes with these being two different women.

2.  1800 Census Index/Images (online at Ancestry.com):  the 1800 VA and KY censuses were lost; Ohio was not yet a state.

3.  1810 Census Index/Images (online at Ancestry.com):  not found, but the 1810 census of Orange County is missing; so was the entire 1810 census of Ohio, except for Washington County.

If Thomas & Winnie are still in Orange County, how is it that their daughter, Mary, was married in Greenup Co., KY?  Is the marriage record not hers?  Or is this couple in the census not our subjects?

Valentine Sampson

120 001 001 - 200 020

These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	4 or under	1825-1830	= William (b. 1830)
2 males	5-9	1820-1825	= Son A = John (b. 1820)
1 male	30-39	1790-1800	= Valentine (b. 1798/9)
1 male	60-69	1760-1770	= ?
2 females	4 or under	1825-1830	= Daughter B = Daughter A
2 females	20-29	1800-1810	= ? = Nancy (b. ca. 1802)

It is conceivable that the elder man is Valentine's widowed father.  It is also conceivable that the elder man is David CORBIN, who married in 1828 in Lawrence Co., OH, to Elizabeth SAMPSON, probable sister of Valentine, whom I cannot otherwise find in the census.

Thomas Lambert married Mary Sampson in Greenup Co., Ky, in Dec. 1816.  She was a daughter of Thomas Sampson.  Both fathers had to give permission since Thomas Lambert and Mary Sampson were both just 16 when they married.

The Dec. 1814, Greenup Co, KY, marriage of Thomas Lambert and Mary Sampson lists that they hand the permission of his father Jonathon Lambert, and her father Thomas Sampson. Information in the Lambert Papers at Marshall University, Special Collections section of James Morrow Library, indicates that Mary was a sister of Valentine Sampson (1799-ca 1856), who married Nancy Higgins (1800-ca1843) in Lawrence Co, OH, on 18 Jan. 1821. Thomas Sampson appears in one or two Lawrence Co tax lists, and is probably the older male with Valentine Sampson and family in the 1830 census. After Nancy died, Valentine married the widow Catherine Neal, and was divorced from her. He married again and died in Missouri, about 1856. In 1856, his son John Sampson filed papers to settle the estate Valentine left in Lawrence Co. when he moved west.

What is Mary doing in Greenup Co., KY, in 1816 if her parents are still in Orange Co., VA, as late as 1820?

Did Dodd really misread he record?  Or did someone else misread it?
