Live in Finland so baby (boy) will have a Finnish name but a key part of my criteria is that its easy for English speakers to pronounce and spell because my family are in the UK and it wouldn't be nice if they get his name wrong all the time but I've been living here too long so I automatically pronounce names the Finnish way so its hard to think how an English speaker would say it.
So these are the options (well so far):
Aslak
Otso
Oskari
Tomi
