My wife is a ggrandaughter of John Thomas Dandridge and Charlotte Castell. I have John Thomas's heritage as follows:
1. Francis Dandridge b. abt 1771 in Drayton, died after 1860. m. Deborah 2. Thomas Dandridge b. before Feb. 24, 1805 in Little Wittenham, m. Jane Powell 3. John Dandridge, b. abt. 1829 in Little Wittingham, m. Martha 4. John Thomas Dandridge b. Oct. 19, 1857 in Dorchester, Oxford, England, d. 1937 in Manitoba, Canada.
Does this agree with what you have? Do I understand that you have earlier ancestors as well?
