My wife's tree contains a Bertha M Hamre (b. 1883 in Wisconsin) who apparently had a brother Andrew who was born nine years earlier (1874) in Norway. Bertha was the second wife of Andrew A. Johnson (b. Wisconsin 1862-64 depending on which census I'm reading). All seem to be from the Dane County region.
Please contact me if you can share information on any or all of these people.
Thanks!
Bill
