George Wren was a stage manager at Laura Keene's theater in Manhattan.

Nora Titone, in her book "My Thoughts Be Bloody" writes that George Wren had a little spat with John Wilkes Booth about Fort Sumpter. When Wren announced he was going to sign up with the Union, Booth responded in anger, saying " he did not doubt but what the South would gain what they were fighting for." Wren later testified that Booth planned to "go into the Southern Service."
