These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	9 or under	1800-1810	= Son C
1 male	10-15	1794-1800	= Son B
1 male	16-25	1784-1794	= Son A
1 male	45 or over	in or bef. 1765	= William
3 females	9 or under	1800-1810	= Daughter E = Daughter D = Daughter C
1 female	10-15	1794-1800	= Daughter B
1 female	16-25	1784-1794	= Daughter A
1 female	45 or over	in or bef. 1765	= Dorothy

Could McGilvery Wyatt (b. 1796/7) be "Son B" and could Druscilla be one of the daughters?

4a.  A.B. Willhite.   [n.d.]  Christian Co., Kentucky, Tax List, 1804-1809.   (Self-published; available from author at 4396 Coopertown Rd., Russellville, KY 42276, or from the Christian County Genealogical Society, Hopkinsville, KY).

Pg. in Willhite	Year	Dist.*	Last  Name	First  Name	A	B	C	D	Acres	Watercourse

Legend for numerical data: A = White Males 21 or over; B = Blacks over 16; C = Total Blacks; D = Horses
*From 1807-1809, the county was divided into just two districts:  East and West.  In 1820, the eastern part of the East Dist. became western Todd Co.  William's location is confirmed by the location of the West Fork of the Red River in today's southwestern Todd Co.

There was a William Wyatt on the 1800 tax rolls, but given the hiatus, it seems unlikely he is the same William Wyatt who appears in 1809.

4b.  A.B. Willhite.   [n.d.]  Christian Co., Kentucky, Tax List, 1810-1813.   (Self-published; available from author at 4396 Coopertown Rd., Russellville, KY 42276, or from the Christian County Genealogical Society, Hopkinsville, KY).   One son (A or B) is over age 16 and living at home.

Given that William sold his land in 1816, could he be this "landless" Wyatt? With the formation of Todd Co. in 1820, the disappearance of these Wyatts from the Christian Co. tax rolls was to be expected.

Pg. in  JTK	Pg. in Book B	Date	Motion
104	274	9 Nov 1812	Ordered that the clerk of this court bind out Drusilla WIATT to John FINLEY according to law.
119	315	3 May 1813	Ordered that McGilvery WYATT of the age of sixteen years be bound to John H. ANDERSON until he attain full age to learn the trade, art and mistery of the cabinet business and that the said ANDERSON enter into Indenture of apprenticeship with the clerk of this Court according to law.

John FINLEY is distantly related to the William T. WYATT (b. 1802/3, TN) who married Rachel THOMPSON in 1825 in Todd Co., KY.   Could McGilvery and Drusilla be children of William and Dorothy?

The first witness on a deed is usually a relative/representative of the husband, and the second witness is usually a relative/representative of the wife.  In other words, these secondary witnesses may be an aid to finding Dorothy's surname.  Reins Lick Creek is a sinking tributary in the watershed of the West Fork of the Red River, just NW of Trenton, Todd Co., KY.  For location of Reins Lick Creek on a map, see Geographic Names Information Service.
