this is somewhat related.. I had a mum come into my work with her child. I needed Their medicare card.. The childs first, middle and surname were hyphenated. all the names were very different. The mother admitted that she thought it as cool and when she had to fill out forms for a passport there wasn't enough room. The mothers name is hyphenated and she thought she'd carry on the tradition with her 3 children. I personally think that's going a bit far.
