James Wallace

These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
3 males	9 or under	1810-1820	= William (b. 1817/8) = Son B = Son A
1 male	10-15	1804-1810	= ?
1 male	26-44	1775-1794	= James (b. 1792/3)
1 female	9 or under	1810-1820	= Daughter A
1 female	26-44	1775-1794	= Isabella (b. 1796/7)
2	persons engaged in agriculture

The teenage male is too old to be their child.  Four children in five years is unusual, but not impossible.  Listed one line below William WALLACE and five lines above Harbert WALLACE.

3a.  Census Index:  U.S. Selected Counties, 1830 (Broderbund CD-315):  Based on the birthplaces of the children, they should be in Tennessee.  The CD shows eleven James WALLACEs in TN, in Anderson, Claiborne, Jackson, Rutherford, and Sumner Cos., but none in Stewart or Montgomery Cos. (see next source).

3b.  1830 Census Index and Digital Images (online at Ancestry.com; Image #X of X; extracted by Diana Gale Matthiesen):  According to their online index, there is a James WALLACE in Stewart Co., TN (p. 44), and one in Montgomery Co., TN (p. 59).  One of these is almost certainly our James, but both of these census page images are missing from the online database (I have notified Ancestry.com of the problem as of 15 Oct 2001.)
