A resident of Lake Providence, Williamson represented the delta parishes: Tensas, Madison, East Carroll, and Concordia,[1] a rich farming region along the Mississippi River.

In 1897, Norris Williamson received his Bachelor of Science degree from Mississippi State University in Starkville, an institution then only seventeen years old.

On July 4, 1897, he relocated to East Carroll Parish in far northeastern Louisiana to become a contractor in the construction of levees along the Mississippi River.

In June 1929, he was named vice-president of the anti-Long Constitutional League of Louisiana, which was organized in the St. Charles Hotel in New Orleans to "save the state from Long".

[6] Williamson retired to private life in 1932, rather than face likely defeat at the hands of the Longites, and his seat passed to Andrew L. Sevier of Tallulah, who remained in the post until his death in 1962.

Whereas Williamson had refused to compromise with the Long faction and retired from politics, Brooks ran again, equivocated in his last campaign regarding Longism and disappointed some of his original supporters who felt that he had not stood by his principles.

[8] Norris and Sally Williamson, who outlived her husband by twenty-seven years, are interred at Lake Providence Cemetery.
