Who was the American in the Kelly Gang?

The American in the Kelly Gang was Joe Byrne, who was a prominent member of the infamous Australian outlaw gang led by Ned Kelly. Byrne was born in Australia to Irish immigrants but spent some time in the United States, which contributed to his American identity. He was known for his intelligence and skills as a bushranger, playing a crucial role in the gang's activities during the late 19th century. His involvement ended when he was killed in a shootout with police in 1880.
