in Finnish is short for Mikael
. New moon in Finnish is 'uusikuu' and that's not used as a first name.
Preita is not a Finnish name at all. (Love
in Finnish is 'rakkaus' - not a name either). Preita seems to be a variant of the Indian name Preet which means 'love'.
I don't know anything about the name Kahlo, I'm sorry. There's a Finnish word 'kahle' which means fetter / chain. Or it might be related to the German
word (and surname) 'kahl' which means bald.
No - that were just wild guesses, I really have no idea! ;)
