1.  There is no available 1790 or 1800 census of  Kentucky.  (See 1800 tax roll below.)

2a.  1810 Census Index (online at GenealogyLibrary.com).  Please see my WARNING regarding use of this database (the genders are switched in the numerical data).  In this particular record, the data are further damaged by a "frame shift."

11100-1120-10

2b.  1790-1870 Census Index (online at Ancestry.com).  These data reflect the same "frame shift," but at least now the genders are in the correct order.

1810

CARDERY

JOHN

Christian

KY

114

1120-11100-10

These data should read:

11201-11001-00

Which indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	9 or under	1800-1810	= Elijah (b. 1805)
1 male	10-15	1794-1800	= James? (b. 1795)
2 males	16-25	1784-1794	= John? (b. ca. 1790) = William? (b. ca. 1788)
1 male	45 or over	in or bef. 1765	= John (b. 1760)
1 female	9 or under	1800-1810	= Sally (b. 1801)
1 female	10-15	1794-1800	= Polly (b. ca. 1798)
1 female	45 or over	in or bef. 1765	= Catherine (b. 1764)

The older boys appear to be William, James, and John Jr., yet there are three males this age living with their eldest son, Charles.  Could John and Catherine have had more than the nine children attributed to them by Eugene Cordry (Source 6 below)?

3.  1820 Census Index (online at GenealogyLibrary.com):

1820	Cordrey, Charles	KY	Todd Co.	p. 133
1820	Cordrey, James	KY	Todd Co.	p. 133
1820	Cordry, John	KY	Todd Co.	p. 133
1820	Cordry, C.	KY	Todd Co.	p. 133

This last is surely Catherine.

*The county was divided into just two districts:  from 1804 to 1806, into North and South Districts; beginning in 1807, into East and West Districts.  The change tells us that John was in the southeast quadrant of early Christian County, which later became the southwest quadrant of Todd Co., when it was formed in 1820.  This location is confirmed by the location of the West Fork of the Red River in today's southwestern Todd Co. Reins Lick Creek is a sinking tributary of the West Fork of the Red River.

Charles Cordry is also on the rolls, with livestock and 200 acres on the West Fork of the Red River (he, too, is missing in 1808).

*Ten-to-one "Clay?" is a misreading of "Caty."  Hard to say who the second James might be.  There should be another "John," not another "Jas."  As expected, the family drops off the tax rolls when Todd Co. is formed in 1820.
[And good grief, the poor man was taxed not only to his grave, but in it!]
