Through several years of genealogical research for my family, I have found the most intriguing and mysterious family history to come from this line in my family tree. In the small, rural area of Central Louisiana, in the area of the Bayou Beouf, there contains a wealth of fascinating history. Along Bayou Boeuf stands many plantation homes as well as the Trinity Episcopal Church which is on the National Register of Historic Places. Mary Dunwoody McCoy is buried there in the cemetery located on the grounds of the church and so are many others, I believe who were involved in creating this rich history.

One of those people is Myrtle Sue Lyles Eakin, known as "Sue Eakin" (December 7, 1918–September 17, 2009). She was an American professor, newspaper columnist, and historian from Bunkie in Avoyelles Parish, who researched Louisiana history, particularly the Old South plantation system. Dr. Eakin is best known for documenting and reviving interest in the 1853 slave account, Twelve Years a Slave by Solomon Northup. 

Eakin's collection of voice recordings is housed at the University of Kentucky. The online catalog can be found here: http://www.kentuckyoralhistory.org/collections/sue-eakin-louisiana-oral-history-collection. Eakin assisted in a recording dated 1st November 1970 of my great grandmother, Mary Dunwoody Burges Wier. The recording was about her life on Bayou Boeuf where she mentioned riding in a horse drawn carriage with her grandmother Mary McCoy. I was able to attain a copy of the sound recording from the University of Kentucky, since their library now houses the historical records taken by Eakin of her hometown area in Central Louisiana. Eakin is buried at the Trinity Episcopal Church in Cheneyville.

Annie Grace Drake is known as the ghost writer for the book: William O'Neal (1827-1907); Or, the Man Who Sold His Wife. Mary Dunwoody McCoy is known for being mentioned in the book, Solomon Northup 12 Years A Slave.
