Jesse and John would appear to be old enough to have been the father of the last three children attributed to Elizabeth. Does the bible explicitly state these are Elizabeth's children?
Just curious about your connection of the Allen Walker from the 1860 census of Sequatchie, TN to the Allen Walker in the James Walker bible. Considering the age listed for Allen in the census would put his birth at abt 1816 and the bible shows 1813, this is maybe an error on the census data(all of the census data being tied to this Allen Walker show different birth years). The previous census year 1850 from Scattering, Marion, TN is probably the same Allen (transcribed as Alien). This means that Nancy, not Barbary was probably the mother of the children you are listing with the exception of Missouri V. Perhaps someone can help debunk or confirm that these two censuses are for the same Allen?
Name: Alien Walker (Allen)
Age: 37 (36 if b Dec 1813?)
Birth Year: abt 1813
Home in 1850 (November 4): Scattering, Marion, Tennessee
Nancey Walker 36 F b NC
Joseph Walker 15 M b TN (Joseph Jesse Walker?) Barley Walker 14 M b TN
John Walker 11 M b TN
William Walker M 7 b TN
James Walker 5 M b TN
Nancey Walker F 4 b TN
Not sure who Nancy is but would love to see a marriage record or some other evidence of her family and Barbary's for that matter.
Other evidence that Barbary was not the mother:
William in 1900 census of Upton, Texas, MO lists Barbary age 72 as step-mother. William never lists his mother's birth states (SC or TN) as the same as Barbary's (GA or NC).
Also - Mila in the 1860 census is believed to be Milo or James Milo who was killed in the Civil War.
The Allen associated with this William and Barbary we believe is the one buried in Wright, MO but there are no dates on his grave just Co. A 6th. Tenn. Mtd. Inf. William is buried in the same place with Co. A 6th. Tenn. Mtd. Inf. on his stone too.
Still not sure however that the Allen that went through Marion/Sequatchie/Hamilton TN to Wright/Texas MO is the same on from the Hawkins, TN bible.
