Here is the same family in the 1930 Dewey County OK, Trail Township Census: 92/98 Howard, Ella, Head, 38, Widowed, KY KY KY Clarence, Son, 21, OK MO KY Lila, Daughter 19, OK MO KY Ethel, Daughter, 17, OK MO KY Emery, Son 17, OK MO KY Elvis, Son, 14, OK MO KY Catherine, Daughter, 11 OK MO KY
It looks like Emery is “Marion Emery” and that Elvis is “Lawrence Elvis”.
I'm still searching earlier census records to find Ella's husband. I'll let you know what I find. Feel free to email me if you want at email@example.com Linda
