Most of people had a Finnish name, but in church book all the names are in Swedish before 1900.
Before 1700 they even were in Latin.
So most of people translate the names in Finnish back to family books. Some use those Swedish and Latin versions.
In Finnish language we do not normally use W but V.
Priests used almost always W.
