Emery Ferrell

I am looking for Emery Ferrell's parents. Emery was born in Missouri abt 1871/74. He married Cora Edna long she also was born in Missouri.
They had five children Nora, Eugene J., Wellington, Raumond O., Walter Duard Ferrell. I found this on the 1920 cencus in Weld, Colorado. They both died there. Any info would be appreciated.
Thank You,
Barbara
