WHile researching the Morthlands in Marion Co, I encountered your D V Morthland and Nellie Lane (her MODC is online) in Yakima WA and am glad to find out who his parents were.
How is Joseph Morrison Morthland related to Hugh Morthland? Hugh Morthland and his wife Sarah Ann Snyder came from Whitley Co, IN to Marion Co MO and are buried there along with many of their children.
Do you know if your D V Morthland was named for the youngest son of Hugh and Sarah Ann Snyder Morthland? In 1870 Hugh and Sarah were enumerated in Whitley Co with a son named Devi S Morthland c.1868. Devi adn DV seem similar. Devi is too old for your D V Morthland but I can't find anything more on Devi.
