What is not clear is whether his surname was Barren, Barzon or Baron.

Barren succeeded Billy Lambe, the Club's first ever coach in their history. In September 1912 FC Barcelona contracted the services of a specific coach for the first time when they brought in this Englishman. What is not clear is whether his surname was Barren, Barzon or Baron, althought the version that appears most in the press of the time is Barren

He was replaced in 1912 in December by Jack Alderson after the Club played a series of friendlies against his team, Auckland Wanderers.
