Do you or can you look up obituary archives? I'm into my genealogy and my Grandmothers family lived in Helsink, I have names and death dates.
Unfortunately we have no orbituary archives at our disposal. The best thing for you to do is to contact the Genealogical Society of Finland and ask the personnel there to assist you in finding the orbituaries. Their address on the Internet is http://www.genealogia.fi/indexe.htm
