*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."

George & Anna are recently wed and, as yet, have no children.  George's twice-widowed mother, Elizabeth (__?__) STRAUBE LOVE, appears to be living with them; and, with four slaves, it's a prosperous household.
