How to get rid of "doubles"?

Dear sirs,

I managed to create doubles of two persons: Juho Vaisanen and Augusta Leinonen. I know how to solve the problem when there is an exclamation mark. But Juho Väisänen is only with a mark 2x. There should be only one Juho V. who is father of Augusta. And Augusta is also one person.

I would appreciate your advise.
