Hi. I found some info for you. First, I started with the 1920 census, assuming that maybe they hadn't married yet. They hadn't. I found John T. with his family, in Bogalusa, Washington Parish. Listed was; John J. Holmes, 49, born Ms., parents Ga., Lizzie 44, Ms., parents Ms., Alma 21, J.T. 20, Rosa 19, Martha 16, Daisy 15, Eva 12, Ella 11, James 6, Allen 3, Melvin 1. On the 1930 census, in Washington Parish was; John T. Holmes 29, Hattie 26, Helen 6, John D. 5, Wila M. 3, William 2. Married when he was 21, she was 19.
John J. and Lizzie are buried in Seal Cem., Washington Parish. John 2-18-1871, 11-27-1930. Lizzie 10-6-1876, 3-29-1957.
I couldn't find Hattie, as a 16/17 year old on the 1920 census, but they may not have been in Washington Parish at that time. Lots of Ellis' in La. Hope some of this helps. Maura Garrett
