Anne, I research the KICKLIGHTER surname. I have seen the reference to Mary Kicklighter, Thomas Kicklighter and Elvira Kicklighter living in the household of Henry Vanadore and Elizabeth. However, I have not been able to find an 1850 SC census online.
Can you give the ages for Henry and Elizabeth in the 1850 census? According to an online 1850 index, there are two Varnadore families listed in Colleton District. One of these families is listed on page 219, the same page as a Kicklighter family.
