re Alexander Phacheas photo

We have long wondered about the the 'A. Phacheas' on my grandfather's marriage certificate who was the male witness at his wedding on the 3 March 1914, in Brisbane, Queensland. Could this be the same person, Alexander Phacheas in the family group photo posted 26 Sep 2013. If it is the same person it would be interesting to find out what Alexander was doing in Queensland at the time and what was his connection to my grandfather.
