Were Fredrik and Anna married at the parish church that is pictured in the link? Maybe. Maybe not, as their first daughter was born only about 2 months after their wedding; did the parish frown upon this, or celebrate the union, sort of a "better late than never" mentality?
Fredrik and Anna remained married until her death in 1893, and had 6 children.
