During the days of the American Frontier, James Hardwick, the "bravest man in Duro County," ran a mining interest there, but always took time out to teach his son Preston how to ride and shoot. Hardwick, originally from the East and with a good family name, was a good man in addition to being a good shooter, and so when he was shot in the back it came as a shock to everyone in town. Preston, who had been out East for the last few years to finish his education, raced back home upon hearing the news. Wishing to see the killer brought to justice, but remembering a promise he had made to his father to never "let gunpowder besmirch the family name," Preston realized his appearance had changed so much while he had been gone that even family friends did not recognize him. He decided, therefore, to take an alias, Red Larabee, and tracked down his father's murderers.[1] After avenging his father's death, Hardwick travelled the west on his horse Terror (later renamed Blaze) earning the reputation of a deadly gunslinger. He became known to people as the Gunhawk, and many an outlaw feared his guns.

I do not have a solid plan for the limited series or how it would follow along with the greater MCU, but there is a summary of how Gunhawk came to be the crime fighting gunslinger he was.
