Lawrence and Nancy Walker, 1860 census

I am looking for information on Lawrence and Nancy Walker who appear in the 1860 census in Assumption, Christian Co IL.With them are children Martha Walker, born about 1843 IL, James born about 1846 IL, Mary R born about 1847 IL, and a daughter whose name I cannot make out (maybe Inez?) born about 1849 in IL.

Lawrence Walker was born about 1806, looks like in NC, and Nancy was born about 1807 in KY. Lawrence Walker died 10 December 1863, and is buried in Greenwood Cemetery in Assumption.

I believe they had an older son, born about 1824, in KY.He was named, get this, Elizabeth!I know from my great grandmother's DC that her parents were L.B. and Sally Walker.And I found them on the 1880 census in Barton Co MO, where Martha Jane Walker's husband grew up.I chased around the sons of L.B. and Sally Walker, and both of their DCs say their father was named Elizabeth!

Elizabeth was my mother's middle name, and I think I now know who she was named after.
