Milton dies in Red Dead Redemption 2. He gets killed by Abigail.

If I had to guess, you're referring to Archer Fordham, Edgar Ross' protegé. No, he's probably still alive as of 1914. The reason why is because:

A. Ross is a glory hound and takes all the credit for killing John and disbanding the Van der Linde gang.

B. Fordham didn't participate in the Beecher's Hope shootout, so Jack likely doesn't even know who he is.

Archer Fordham not Milton.

Milton got a head shot from Abigail
