Dan Reid Sr.

Dan Reid Sr. was a Texas Ranger, and the brother of John Reid, the man who becomes the Lone Ranger.

History
In most versions of the Lone Ranger story, Dan Reid is a captain in the Texas Rangers. He leads the group of six Rangers who follow Collins into the ambush at Bryant's Gap. Dan is killed in that ambush, leaving behind his wife, Linda, and baby boy, Dan Jr., who are travelling to Texas from the east.

Dynamite Entertainment
In Dynamite Entertainment's comic book update of the Lone Ranger, Dan Reid does not lead the Rangers into Bryant's Gap. He is a part of the group of six Rangers, led by his father, James Reid. Dan is killed in the ambush, leaving behind his wife and baby boy, who are living in Wyoming.
