Who is Delos? I keep bumping into him. He was an artist, I think. He is buried in Natchez with the family of William Pepperell Mellen. He was born 8/3/1859, died 2/23/1933. He married Corinne Castellanos (1863-5/5/1909) on 11/23/1887 in New Orleans. She was an artist and you can find her work online. They had children: William Francis b. 3/30/1890; Marian b. 10/2/1891; Joseph Grenville b. 9/17/1888 - all born in New Orleans. They may have had more.
This information tells me he is related to Wm P. He named one child after Grenville who died in the war and another after Wm P's William Francis. Is he Wm F's son?
