I do not think that the Sally listed in the 1860 census can be his wife. His wife, Mary Polly (age 75) is for some reason listed in the household of their son George Maxwell that year. Were they really divorced, or was she so ill that her son's family was taking care of her??? This is kind of fishy, but I DO know that our Overton County/Putnam County Joel Maxwell is NOT the same one that ended up in Mississippi
