Who had the male lead role in the early American western film, 'Horseman of the Plains'?

They say he wept at Wyatt Earps funeral.He was a pallbearer and friend

My grandfather spoke often of meeting Tom Mix when he was just a boy. Grandpa was out riding horses with his brother and Tom Mix complimented their cowboy outfits. It made their day.

He and William S. Hart were pall bearers at Wyatt Earp's funeral in 1929.

side note: John Wayne became friends with Earp also while working as page boy at the studio in the 1920's.

saw him a couple times, sorta primitive, comparatively, Gene Autrey was my hero, good western, Roy and Dale Rogers more modern with Nellybell the Jeep.

Radakyl, yes, I have also read that too?
