I was able to find S B Wells in 1910, District 41, Rose Hil, Duplin, NC:

Dwelling 188, Family 189
Samuel B Wells HOH 30 w/m, 1880 GA
Annie E. wife 23, w/f
Annie D., dtr, 10/12, w/f
Thomas J Carr, boarder, 86, w/m

The family listed immediately before them on the census page:

Dwelling 187, Family 188
Rhoda MATTHIS, HOH, 48, b/f, single, NC/all, gen farmer (Laura's sister-in-law?)
Nellie JAMES, 16, b/f, niece
Harriet MATTHIS, 16, b/f, niece (Hattie?)
Walter MATTHIS, 12, b/m, nephew
Mattie MATTHIS, 26, b/f, sister (to Rhoda)

On the next page:

Dwelling 191, Family 192
Henry MATTHIS, HOH, 29, b/m, married,
Carnie, wife, 24
Lucile, dtr, 3
Carmie, dtr, 9/12
May B McMILLAN, step-dtr, 4
Abram BOWEN, boarder, 18, b/m, single, farm laborer, working out
Ross Matthis, 18, b/m, single, farm laborer, working out, brother (to Henry)
Solomon Matthis 23, b/m, single, farm laborer, working out, brother (to Henry)

Interestingly, was able to find white families enumerated in this district with surname MATTHEWS, but all the AA's seemed to have surname MATTHIS. Don't know if you have this info already, though.
