Thanks for the link, is says on the second page

A name cannot be approved as the first forename of a minor child, if it is the first forename of a living sibling or half sibling of the person being named, or if it is a name ending in poika ("son") or tytär ("daughter") or a name formed in a corresponding manner, unless there are special reasons for this.

I could have just dumped my link and been done with it but I wanted to do more than provide a statement without a source, since that (no source) was the reason for my comment to being with. :-)
