So, I am working on uncovering what the source notation, of "Dorothy of the George Christian Wampler site", thought listed that involved Stuart David, Clarence Augusta, and Harvey George Wampler. I have the Wampler/Wampfler Database listing of children for Clarence Augusta Wampler, and his wife - Martha Janie Johnson, differing, or incomplete, in comparison to the listing of children shared for the couple on Martha Janie Johnson Wampler's FindaGrave Memorial page.
Using the Database's information, Harvey George Wampler and Dorothy Elizabeth Candler, daughter of Singleton Candler and Adeline Harriet Bausell, married March 21, 1864 in Russell County, Virginia and were the parents of Clarence Augusta Wampler. A 1900 US Census, for Ervington District, Dickenson County, Virginia helps to confirm this connection as, in the household of Harvey G. and Dortha E. Wampler, there is a Clarence A. Wampler listed as their son, along with another son, John T. Wampler. So, with one source of information, we have already added a sibling for Clarence Augusta Wampler.
(As a side note, the couple also had two lodgers listed on the 1900 US Census report: Douglas Beverly (age 5) and Nora L. Castle (age 3). I am sharing this information now as it may, or may not, be of use in the future within the family tree thoughts.)
Anyway, thanks to this one census report, it appears that Harvey G. Wampler and Dorothy Elizabeth Chandler had at least two children. I also found online Virginia Birth & Christening records for (Martha) Allis (Alice), David C., a male child born May 1, 1867, and Mary A. Wampler; Virginia Marriage for Arnold A. Wampler to Louisa J. Rasnake; and Tennessee Death record for Tabitha Ellen Wampler Hillman. The May 1, 1867 birth record closely matches with information for Casaway T. Wampler whose birth date, on some sources, is listed as May 5, 1867.
With these handful of records and the 1870 US Census report, I have the following nine children for Harvey George Wampler and Dorothy Elizabeth Candler: Martha Alice, William R., Tabitha Ellen, Arnold A., Casaway T., Clarence A., David C., John T., and Mary A. Wampler.
Harvey George Wampler is mentioned another time, within the Wampler/Wampfler Database in reference to one of his nephews:

However, now I can backtrack to the cryptic source notation thoughts, shared with Stuart David Wampler's entry on the Wampler/Wampfler Database that led to Harvey George Wampler, of "Dorothy of the George Christian Wampler site". Without knowing what was actually shared, I am speculating that Dorothy may have supplied information to help verify Harvey George Wampler as the son of George Christian Wampler and his wife, Mary. On Harvey George Wampler's marriage license information his parents listed being Christian and Mary Wampler.
In the process I also managed to uncover more information about Harvey George Wampler (3rd cousin 3x removed to me), Dorothy Elizabeth Candler, and their children (4th cousins twice removed to me).
