Marriage notice in the "Selma Courier" newspaper (Dallas County, Alabama) - 31st January 1828:
"Married, in Butler County, on the 17th inst. by the Rev. John Purdue, Mr. Alexander Watson, recently of this county, to Miss Nancy P. Purdue, of Butler County."
Since Butler County's courthouse burned in 1853, this marriage announcement may help new researchers as well as those who already knew that Nancy Perdue married Alex. Watson, but didn't have official/public documentation.
