Three of their children were born in Tennessee {1838 and 1840 and 1843}.
After migrating to Texas, Lucy Ann and Weston became the parents of twin girls,
born 17 Feb 1854 in Goliad Co., TX.

Perhaps a sister to Lucy Ann, Mary Elizabeth Williams, born in NC, married
Weston's brother, Gibson Whitenton in TN 20 Aug 1840. Gibson and Mary Elizabeth
also migrated to TX and the families lived in close proximity in Goliad Co., TX

I have not researched this Surname further than a single clue that indicates the father
of Lucy Ann is probably James Williams, who deeded land to Weston in Johnston Co., NC
Feb 1833.
