Henry Sumner, son of John and Rebecca, married Pricey Rose in Dickenson Co., VA., in 1908. He's on the 1910 census there. Henry died before 1918, as that's about when Pricey and Richard Fuller married.
Here is Pricey's Old Regular Baptist Church Obituary:
DIXON, Pricey Fuller B: around 1893; D: 22 October 1980. Parents: William Rose & Ruthie Moore. Married (1): Henry Sumner, 1909/1910.Children: Arvil, recently deceased, Dora, deceased in 1927. Married (2): Richard "Dick" Fuller. Deceased 1955. No children this marriage. 1 step-son: Fred M. Fuller. Married (3): Harmon Dixon who deceased 1973. Baptized: Around 1920. Written by her stepson, Fred M. Fuller.
I have never found any record of Arvil except for this one. Dora is on Pricey and Richard Fuller's 1920 census. Also Harmon Dixon should be Herman Dixon.
