What do you think to our name's we have picked?

I'm not very keen on the whole hyphenated-names thing, I think it can be over the top. Why don't you add the second hyphen names as middle names and if the child chooses they can hyphenate later on. That's what I did (my parents christened me Hanna, with Louise as a middle name but when I got to about 14 I changed it to hyphenated Hanna-Louise and everyone calls me Hanna-Lou). It gives the kid a chance to have a choice.
