It will be a good idea to post your message to the main forum board at http://www.afrigeneas.com/forum/ where there are a number of people to help with family research questions. If you are only interested in tracing the Native American ancestry, also post to the African-Native American Genealogy forum at http://afrigeneas.com/forume/. Also, be sure to include time frames and county/state of where your ancestors lived in your post to get better/quicker assistance.
The Family Reunion forum focuses on family reunion planning, ideas, resources, issues, etc.
Good Luck in Your Research!
