Foster, John L.	Chrisman, Elizabeth [Mrs]	24 Mar 1848	Jackson Co.
Chrisman, Ewing	Foster, Martha	10 Apr 1848	Jackson Co.

There were children of other CHRISMAN families marrying in Jackson Co. about this time, so I can't be certain the Ewing CHRISMAN who married Martha FOSTER is the son of our subjects, but it seems highly likely.  Unfortunately, I cannot find Ewing in the 1850 census — anyone know where he was?

These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	19-25*	1794-1801	= Charles (b. 1793)
1 female	16-25	1794-1804	= Elizabeth (b. 1802/3)
1	person engaged in agriculture
*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."

All I can confidently say about "Martha's" name is that it begins with an "M" and has a "t" towards the end.
