Della's father was a farmer in Lavaca County, but the Storm of 1900 forced him to seek employment in the boomtown Guffey, Texas (later known as Spindletop). In November of the 1903, after harvesting their crops, the family left Lavaca County in four wagons during a terrible rainy season. Della and her sisters met their husbands at Guffey where the family ran a boarding house; the daughters assisted their mother in the preparation and serving of meals.
She married Otho Oscar Baker, 15 March 1905, at the Methodist Church in Guffey where the family had its membership. They had two children, Beatrice Pearl "Bea" and James Herman Baker, however their son died, an infant. After Otho and Della were divorced, she and her daughter worked to support themselves during the Great Depression.
Della McGlaun Baker died, 12 November 1958, aged 73, in Beaumont, Texas, and was buried with her infant son in the Baker family plot at Magnolia Cemetery.
