No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	9 or under	1810-1820	= Son A
1 male	19-25*	1794-1801	= Drury (b. ca. 1794)
1 female	16-25	1794-1804	= Mary (b. ca. 1798)
*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25; therefore, any individual in column three is duplicated in column four.  By subtracting the number in column three from the number in column four, you can create an age class "19-25."
