Facts and Events
I didn't find Joseph in 1840 census, but a widow Martha Dugger appeared on the 1840 census in Giles Co, TN. I don't know for sure if this is the same Martha, wife of Joseph, but it seems likely, especially since some of Joseph's siblings lived in that county already. Analysis:
I didn't find Martha on the 1850 census in Giles Co, TN. More research is needed on this branch of the family.
