|Effingham County, Georgia, as of 1825 (map from http://www.randymajors.com/p/maps.html)|
I found a typed transcription on ancestry.com of Christian's will which says the will was dated October 18, 1808, and probated on April 3, 1809. Since Elizabeth is mentioned in his will, she must have died at least after the will was probated. They were still living in Effingham County when Christian died.
