Counties in Sweden help distinguish between parishes with the same name. Finland has no parishes with the same name as far as I know, so parish name and country puts you in the right area. I know of one exception to the rule, Salo used to be the name of a parish far up north on the west coast. It is now called Saloinen and Salo is a town in southern Finland, though most of the church books available to us have it as Salo-Uskela or Uskela, that is the parish where the town is situated. There are also other big towns that have both a city parish and a rural parish named alike, sometimes even a military parish, but they would always be in the same area.
There will always be people who do it their own way regardless of rules or recommendations, but I would like for us to be able to agree upon a place naming recommendation from smallest to biggest.
That would be Farm, Village, Parish, Country. Many times in marriage records the place of the wedding would not be mentioned, and the only thing you can use is the Parish and Country unless a source for the place of the wedding can be found elsewhere.
