Sorry, I have no relatives from GA, neither do I have relatives named congos, congus nor conglia, that I know of. I'm having a very hard time tracing the Congo side of my family. Can't get past my g-grandfather, Winfield Scott Congo. I wish you good luck. Have you looked on the LDS familysearch.org website? That's the Latter Day Saints web site.
