Heikki!
Just reading over this thread and thinking about you naming the little one.
I looked at a site that gives Finnish names and
there are lots of nice names listed.
A thought--how about one that is easily interpreted around the world. As the little one grows older our societies will increase their travels and interactions. Having a Finnish name that is easily recognized everywhere might be an advantage. Just an idea.
e.g. for a girl names such as 'Saara' 'Liisa' 'Kirsti' etc.
for a boy--- 'Fredrik' 'Tuomas' (Tom) 'Timo' (Tim)
Whatever you pick I'm sure will suit that little one.
Best wishes, George
