From the Lewis County, Tennessee Marriages, I found that Nathaniel Brewer and Alice Bartlett were
married  31 October 1880 in that County.  Notice from the 1910 census that Alice indicates that this
is her 2nd Marriage.  It's possible that their son Ed listed in 1900 was actually her son from a
previous marriage.
