With so many hyphenated surnames shared amongst our Warriors I was reminded of how few there were back in the day (reading a NSWRL Player Lists book, published 1994).
Polla-Mounter was one I always remembered. I think two surnames was originally a posh thing. He went to a private school, which might make sense of his posh name. These days? Who knows why parents do it.
Edit: just on ABC Radio, it's a world record, the most hypenated names in a top-level rugby league game, ever. Warriors v Parra, our six and their one.
