Need help with Cook family

I just started the Cook family line and I am in need of help. So far all I know is my great grandpa's name was Julius Fanny Cook b. aug. 7, 1894 at Laflin,MO. He was married to Lola May Jackson. Julius dad was William C. Cook b. march 20, 1860 in Bollinger Co.MO.and he was married to Nancy Hartle. William's mom and dad were John Cook and Melvina(last name unknown). William C. and Melvina had 10 children: Daniel, David, Marion, George, Jesse, William C., Stuffle, Emanuel, Pernicia, and Anna. If any of these names are in your family line please let me know. Thanks
