The first thing you should do is put the ancestor's surname in the subject line. That way viewers will know what family you are searching for. Simply putting "ancestor quest" is too vague, and most people will not even bother to read your email query. If you have a time frame that would be helpful, such as "Chasey and Whiten, 1850-1910." There are Whittens in Tallahatchie County, MS. Good luck.
