Don, I am new to researching family geneologies, but I've been able to trace my husband's family to Elbert William Revelle through his son John D. Revelle, Isaac B's brother. I would be very interested in any info you might have concerning the Revelle line going through Elbert back to North Carolina. If you have any questions let me know via E-mail at email@example.com and I'll try to answer them. Thanks. Jannette.
