I'm not related nor did I know the Bright family. However, I do enjoy genealogical research.
I found one Vernon Bright, born in Virginia, of the right age to be your grandfather.He was in the 1910 census for Tillsman, Brunswick County, Virginia.The household consisted of: ParentP B BrightM 48y ParentClaracy BrightF 44y Child James Michael BrightM 28y Child Lillie Bill BrightF 19y Child Pattie BrightF 17y Child Vernon BrightM 16y Child Millie BrightF 13y Child Joshua BrightM 11y Child Maggie Lee BrightF 9y Child Rena A BrightF 6y Child Robert A BrightM 3y

I tried to find Ola Jones, born in Arkansas around 1914-1916, however there were several to choose from, and I wasn't sure which would be your grandmother.You could check www.familysearch.org to see if any of the Ola Joneses have siblings that sound familiar to your father.
