My grandmother's second husband was James Frank Candler of Marshall and Madison County, NC. He was born in 1861 according to his death certificate (other records indicate 1865-1866) and died in 1925. His parents are also listed as Zack Candler and Amanda Thomas. He is buried at Tillery Cemetery in Madison Co., NC. I have done some research on this family for my mother's half-brother Charles Candler, son of James Frank Candler. I think your Chales N. Candler is a brother of James Frank Candler and the one my uncle Charles Candler was named after.
I have the following children listed of Zachariah and Amanda Thomas Candler. 1. Thomas I. b. ca 1850 2. Martha E. b. ca 1852 3. Charles b. ca 1854 4. Lucinda b. ca 1855 5. George W. b. ca 1858 6. Zachariah b. ca 1860 7. Matilda b. ca 1863 8. James F. b. ca 1865-6 9. Marion b. ca 1869 10. William H. b. ca 1871
I have some evidence to show that Zachariah Candler was the son of Thomas Jefferson Candler, who was the son of Zachariah I. and Mary Boone Candler. I also have some information on Amanda Thomas and think she was the daughter of Peter and Martha Thomas.
My uncle Charles Candler is alert and active at 80 and very interested in his Candler genealogy.
Hope this helps.
P. S. I am also researching the Proffitts and may be able to figure out where Srah Elizabeth Proffitt fits in the family too.
