Lucy A. Buie married Archiblad McPhatter December 1841 in Cumberland Co. NC

1850 Census Cumberland Co. (West), NC 1850, pg. 44, Dwelling# 695, Family # 708 lists:
Archibald McPhatter     28        M        Laborer
Lucy A.    30        F
George W.                             8          M
Daniel J.                                 6          M
Susannah                               1          F
Sarah Buie                         22         F
Margaret Buie                    15         F

This indicates that this could not be the Lucy Buie, widow of Duncan Buie as speculated in Family Group GG by the authors, by being 20 years to young.
Also note Margaret Buie age 15, is the only Margaret Buie of that age in the 1850 NC census, and may be the daughter of Hugh Buie as stated in the Declaration of Widow's Pension by Deliliah Baker Buie (Family Group Z)
Also note in household Sarah Buie aged 22.

Speculation: Lucy A. Buie, Sarah Buie and Margaret Buie, the three unknown daughters of Hugh Buie.  By comparison with the 1830, 1840, NC. census of females in Hugh Buie Household would make them the right ages and since both of their parents are dead by 1850, they may have stayed together????  Also note have been unable to locate Archibald McPhatter and family as well as Sarah and Margaret Buie after 1850 in North Carolina.

James Buie of Darlington, SC and Family Group LL also Hugh's son
