Lydia Box McCollum Lawsuit Against Her Brother, Grief J. Box

Lydia Box, daughter of Michael and Mary (Fulcher) Box, was born about 1808/1810 in Tuscaloosa, Alabama. She is most likely the 20-23 year old female listed in the 1830 Census of Fayette County, Alabama for the Michael Box family.
In about 1830 Lydia married George McCollum. They both appear as original landowners in Fayette County, Alabama. Lydia and George moved to Tippah County with the rest of the Box Family in about 1838.
The family of George and Lydia McCollum (at least 1 son and 3 daughters) was  found in the 1840 Tippah County, MS census and 1845 Tippah, Mississippi State Census.  In 1874, Clarkey Carpenter Box (wife of Thomas Box), gave information to the LDS church stating she had a sister-in-law by the name of Lydia Box, who was born in Tuscaloosa, Alabama. Clarkey Box also mentioned a niece, Martha McCollum, who would have been one of the daughters of Lydia and George McCollum.
Lydia Box McCollum and her husband, George, sued her brother, Grief Johnson Box, over the mishandling of their father Michael Box's estate. Below are the first two pages of the 1847 Mississippi Supreme Court Case, McCullom vs Box. The complete case can be found online at Google Books.

Lydia and George cannot be found in Tippah County records after the 1847 lawsuit.  Where did they go?  Any additional information on this family would be appreciated.

***Update 2013***

In 1850, Lydia and George moved to Henderson County, Texas. Lydia's brother, Thomas Box lived in Henderson County, Texas at that same time.  From George McCollum's 1855/1856 probate papers in Henderson County, five children are known: Mary, Martha, Melissa, George, and William.   More information on Lydia and George McCollum can be found here.
