Hi There,

I too did not want a name that was too popular but I fell in love with the name Matilda so no matter how popular it is becoming I named my DD Matilda!
Anyway, if you google the birth deaths and marriages website for your state you can see the top 10 - 100 names for boy/girl and even pick a year or decade, Finn is in the top 100 for the year 2007 (103 in NSW), but near the bottom. Just thought that this may be of interest to you.
I personally think Finn is a great name and if you like it go for it!

Deanne.
