Finnish Heros

Hi everyone! I just found this page while trying to find my ancestors on the net (succeeded very badly..) I don't know much about my family and I was just wondering if some of you knew more.. Do you really think that all the Heros are really somehow related? All I know about the Finnish Heros that we all got this last name from my grandfather Eero Hero. I've heard two stories about the history of my name: first that it's a "translation" from Herold (so from Sweden) and second that it comes from Belgium. What do you think? There are two lines of Heros here in Finland: us, the decendants of Eero and the decendants of his wife's children from her previous marriage. There are about 13+10 of us. Thank you for reading this through and please, if you know anything...
