Joseph Lonzo Markley& Nancy L (MILES) Markley

I am looking for information about my great grandparents. They are Joseph Lonzo Markley and Nancy Louella (MILES)Markley. I read a couple other enquires but couldn't answer them directlly for some reason. But Joseph Lonzo was the one married to Nancy L Miles. I have their original marriage certificate. Albert Joseph markley was my Great uncle. He lived upstairs over us in an apartment with my Grandmother Hattie(Markley)Eckman.Joseph and Nancy had I think 12 children . They were Austin Adolph, Amos Franklin, Fredrick wayne, Albert joseph,Barny Miller,Hattie Emma ( MY Grandmother )Amanda melvinny, Grace, janie, Goldie Irene,and Mae and I can't recall the other one's name. I would love to find out who joseph's parents were. I'm pretty sure Nancy's were William and Sibyll miles. thank you
