The Oldham-Harris' of DFW TEXAS

I am trying to find information on the parents of Patrick Clead Harris. His father's name was William Harris, some family records show the middle name as "Quarl", others have an "S". His mother was Victoria Rena O'Neal. Family records indicate they both died in 1918. There are so many William Harris' that it is very difficult to find this one. Patrick had a brother named Henry and a sister named Maude. He was born in Ft. Worth, Texas. I have indication of where his parents were born.
