I believe his paternal grandparents were Wilfred Magnussen and Ruth D. Wilfred was the son of Oscar M. Magnussen/Magnusen, whose parents, Magnus Magnussen and Walborg Israelsen, were Norwegian, and of Bertha F. Muhlhauser/Mulhouser (who was the daughter of Louis/Lewis Muhlhauser and Frederica Bertha Goldstein).
