She was born in Finland (Ala Torneå)according to one of the attachments from a household examination record that I posted earlier in this thread. Her last name looks like Kesti in that record. The marriage date there was 27 October 1900.
I've attached both sides of their banns and marriage record.http://www.arkivdigital.net
