How do I enter Scandinavian names into Family Tree?
Help article mentions Finland as it also used patronymic naming system. It says also:"Different endings were used in different countries." Then it gives those endings to all other Nordic Countries, but Finland is missing.
It is true that in Finland long time Swedish names were used in church records but in some sources also Finnish names can be found from that time period and then since 1870-1880 all records had to be kept in Finnish.
Please add to the Help article Finnish endings -poika and -tytär.
