Dan Reid Jr. was a baby traveling with his mother, Linda, from Virginia to be with his father, Dan Sr., in Texas. During the time they were traveling, Dan Sr. was killed in an ambush at Bryant's Gap. As their wagon train neared Fort Laramie, it was attacked by renegade indians. Linda was killed, but first she hid little Dan in a trunk. An old lady traveling with the party, known as Grandma Frisby, managed to sneak away with Dan in the chaos.
Grandma Frisby eventually settled near the Canadian border, and took Dan to be her own grandson. As Dan reached his early teens, the Lone Ranger was brought north in pursuit of an outlaw trying to cross the border to Canada. The excitement was too much for the old woman's weak heart. Before she passed on she revealed the story of Dan's past to the Lone Ranger. She gave the Ranger a locket she had found with Dan. In it were pictures of Dan Sr. and Linda, revealing the boy to be the Lone Ranger's long-lost nephew.
When Dan grew up he got married and had a son, Britt Reid, who became a masked crime-fighter known as the Green Hornet.
