I haven't been able to find any information on Sally Perdue or Susan Perdue but I assume Susan is her mother? I just can't find any concrete evidence of it.
Here is what I have on Benjamin:
1825: Stokes Co., NC marriage bond: Benjamin Vermillion and Rebecca Roberson
1830 NC census: 1 male 20-30yo, 1 female 20-30yo, 1 female under 5yo
1840 Stokes Co., NC Census: Benjamin Vermilion(sp) 1 male 30-40yo, 1 male 6-10yo, 1 female 30-40yo
1850 Stokes Co., NC census: Benjamin Vermillion (50yo) living with Alexander Miller and James S. Sapp
1856: Benjamin Vermillion marriage to Sally Perdue, Forsyth Co., NC
1860 Forsyth Co., NC census: Benjamin Vermillion (54yo?), Sarah(55yo?), William H. (2yo).
1870: Forsyth Co., NC census: Benjamin Vermillion (69yo), Sarah (30yo? illegibal), Harrison (12), Joshua (9yo), Susan Perdue (85yo).
1880 census: No record of Benjamin; Harrison Vermillion (20yo, single), Susan Perdew(sp) (82yo, widowed).
1882: Forsyth, NC: Benjamin Vermillion and Sarah Vermillion in Marriage record of Jehu Vermillion(b. 1862) and Susan Dillon(b. 1863)
1894: Benjamin Vermillion and Sallie(sp) listed as deceased on marriage license of William Harrison Vermillion.
Sally (Sallie) is found in 3 places:
1) 1856 Marriage license between Benjamin Vermillion and Sally Perdue.
2) 1894 Marriage license for William Harrison Vermillion and Ella Carmichael. (Sally)
3) 1921 Death certificate of William Harrison Vermillion. (Sallie)
