I am particularly interested in Norrbotten as that is where most (all?) of my Swedish ancestors seem to have lived.
Daniel Nordlund's DNA has been tested for genealogical purposes. It may be possible to confirm family relationships by comparing test results with Daniel or other carriers of his ancestors' Y-chromosome or mitochondrial DNA.
It is likely that these autosomal DNA test-takers will share DNA with Daniel:
