No. & Sex	Age Class	Therefore Born	Individuals Inferred
2 white males	4 or under	1835-1840	= J. M. (b. 1837/8) = George R. (b. 1835/6)
1 white male	15-19	1820-1825	= ?
1 white male	20-29	1810-1820	= Christopher
1 white female	5-9	1830-1835	= Daughter A
1 white female	15-19	1820-1825	= Hester (b. 1821/2)
1 male slave	24-35	1804-1816	= ?
1 female slave	10-23	1816-1830	= ?
2	persons employed in manufacture and trades

The teenage male is too old to be Christopher's son.  If the young girl is Christopher's daughter, it's looking like he may have had a prior wife.
