In reply to your question of whether Mildred Duty is related to Sarah Louisiana Duty, YES! I have recently received data on the Duty family and will gladly share the data with you. I also have photos of Morgan Cryer, Jr & Wiley Powell Cryer (Morgan's great-grandson) grave marker. You can view the photos on my website: http://freepages.genealogy.rootsweb.com/~mobleyb/Index.htmlhttp://freepages.genealogy.rootsweb.com/~mobleyb/Index.html
If you would like to receive a copy of the "Duty" info, drop me a line and I will send it to you.
