Hitch? Boyd on Cooksey Ranch

The first name is difficult to read. The horse is a sorrel mare named Cookie that my granddad Lois Campbell bought when he lived on the ranch he bought west of Carlsbad NM from Frank Jones in the 1940s.

Somehow this is connected with my mother's family. Her dad Lois Campbell worked on several ranches in the west TX, eastern NM area during the 1930's-1940's. I would like to place this ranch & person. Possibly connected to Willie R Brown (Dick) or Anna Lois Campbell Brown, lived Carlsbad NM 1940s-60s.
