Who was that masked man??

Question

What was the name of the Texas Ranger who became the Lone Ranger, and who was his great-grand nephew?

My error, not his great-grand nephew or his nephew, but his grand nephew (his nephew's son.).

Unfortunately; no one came up with the answers.
The Texas Ranger who became the Lone Ranger was John Reid.
His brother (killed in the ambush that catalyzed John's transformation) was Dan and his nephew was also named Dan.
His grand-nephew's name was Britt Reid, aka the Green Hornet.

Answer 1

His nephew was Dan Reid, the Lone Ranger's name was never mentioned..

Answer 2

Jim Clark His nephew was Dan Reid
