In the 1880 census,Colleton County,George Township, city of George,S.C., is listed Carrie Pendarvis, white, female, age 9. She is enumerated in the home of Mary E. Risher
I knew another person several years ago who was searching for children of Jake Pendarvis and this Carrie was thought to be one of his children. Could your Elizabeth Caroline Pendarvis have been called "Carrie"? If you think this might be a match and you would like to contact that person, e-mail me and I will give you her U.S. Mail address at that time. Don't know if her address would still be the same or not, but might be worth a try. We corresponded for some time, so I may have further info. in my files somewhere.
